The City of God, Volume II

28. Of the change of name in Abraham and Sarah, who received the gift of fecundity when they were incapable of regeneration owing to the barrenness of one, and the old age of both.

Now when a promise so great and clear was made to Abraham, in which it was so plainly said to him, "I have made thee a father of many nations, and I will increase thee exceedingly, and I will make nations of thee, and kings shall go forth of thee. And I will give thee a son of Sarah; and I will bless him, and he shall become nations, and kings of nations shall be of him,"291– a promise which we now see fulfilled in Christ, – from that time forward this couple are not called in Scripture, as formerly, Abram and Sarai, but Abraham and Sarah, as we have called them from the first, for every one does so now. The reason why the name of Abraham was changed is given: "For," He says, "I have made thee a father of many nations." This, then, is to be understood to be the meaning of Abraham; but Abram, as he was formerly called, means "exalted father." The reason of the change of Sarah's name is not given; but as those say who have written interpretations of the Hebrew names contained in these books, Sarah means "my princess," and Sarai "strength." Whence it is written in the Epistle to the Hebrews, "Through faith also Sarah herself received strength to conceive seed."292 For both were old, as the Scripture testifies; but she was also barren, and had ceased to menstruate, so that she could no longer bear children even if she had not been barren. Further, if a woman is advanced in years, yet still retains the custom of women, she can bear children to a young man, but not to an old man, although that same old man can beget, but only of a young woman; as after Sarah's death Abraham could of Keturah, because he met with her in her lively age. This, then, is what the apostle mentions as wonderful, saying, besides, that Abraham's body was now dead;293 because at that age he was no longer able to beget children of any woman who retained now only a small part of her natural vigour. Of course we must understand that his body was dead only to some purposes, not to all; for if it was so to all, it would no longer be the aged body of a living man, but the corpse of a dead one. Although that question, how Abraham begot children of Keturah, is usually solved in this way, that the gift of begetting which he received from the Lord, remained even after the death of his wife, yet I think that solution of the question which I have followed is preferable, because, although in our days an old man of a hundred years can beget children of no woman, it was not so then, when men still lived so long that a hundred years did not yet bring on them the decrepitude of old age.

29. Of the three men or angels, in whom the Lord is related to have appeared to Abraham at the oak of Mamre

God appeared again to Abraham at the oak of Mamre in three men, who it is not to be doubted were angels, although some think that one of them was Christ, and assert that He was visible before He put on flesh. Now it belongs to the divine power, and invisible, incorporeal, and incommutable nature, without changing itself at all, to appear even to mortal men, not by what it is, but by what is subject to it. And what is not subject to it? Yet if they try to establish that one of these three was Christ by the fact that, although he saw three, he addressed the Lord in the singular, as it is written, "And, lo, three men stood by him: and, when he saw them, he ran to meet them from the tent-door, and worshipped toward the ground, and said, Lord, if I have found favour before thee,"294 etc.; why do they not advert to this also, that when two of them came to destroy the Sodomites, while Abraham still spoke to one, calling him Lord, and interceding that he would not destroy the righteous along with the wicked in Sodom, Lot received these two in such a way that he too in his conversation with them addressed the Lord in the singular? For after saying to them in the plural, "Behold, my lords, turn aside into your servant's house,"295 etc., yet it is afterwards said, "And the angels laid hold upon his hand, and the hand of his wife, and the hands of his two daughters, because the Lord was merciful unto him. And it came to pass, whenever they had led him forth abroad, that they said, Save thy life; look not behind thee, neither stay thou in all this region: save thyself in the mountain, lest thou be caught. And Lot said unto them, I pray thee, Lord, since thy servant hath found grace in thy sight,"296 etc. And then after these words the Lord also answered him in the singular, although He was in two angels, saying, "See, I have accepted thy face,"297 etc. This makes it much more credible that both Abraham in the three men and Lot in the two recognised the Lord, addressing Him in the singular number, even when they were addressing men; for they received them as they did for no other reason than that they might minister human refection to them as men who needed it. Yet there was about them something so excellent, that those who showed them hospitality as men could not doubt that God was in them as He was wont to be in the prophets, and therefore sometimes addressed them in the plural, and sometimes God in them in the singular. But that they were angels the Scripture testifies, not only in this book of Genesis, in which these transactions are related, but also in the Epistle to the Hebrews, where in praising hospitality it is said, "For thereby some have entertained angels unawares."298 By these three men, then, when a son Isaac was again promised to Abraham by Sarah, such a divine oracle was also given that it was said, "Abraham shall become a great and numerous nation, and all the nations of the earth shall be blessed in him."299 And here these two things are promised with the utmost brevity and fulness, – the nation of Israel according to the flesh, and all nations according to faith.

30. Of Lot's deliverance from Sodom, and its consumption by fire from heaven; and of Abimelech, whose lust could not harm Sarah's chastity

After this promise Lot was delivered out of Sodom, and a fiery rain from heaven turned into ashes that whole region of the impious city, where custom had made sodomy as prevalent as laws have elsewhere made other kinds of wickedness. But this punishment of theirs was a specimen of the divine judgment to come. For what is meant by the angels forbidding those who were delivered to look back, but that we are not to look back in heart to the old life which, being regenerated through grace, we have put off, if we think to escape the last judgment? Lot's wife, indeed, when she looked back, remained, and, being turned into salt, furnished to believing men a condiment by which to savour somewhat the warning to be drawn from that example. Then Abraham did again at Gerar, with Abimelech the king of that city, what he had done in Egypt about his wife, and received her back untouched in the same way. On this occasion, when the king rebuked Abraham for not saying she was his wife, and calling her his sister, he explained what he had been afraid of, and added this further, "And yet indeed she is my sister by the father's side, but not by the mother's;"300 for she was Abraham's sister by his own father, and so near of kin. But her beauty was so great, that even at that advanced age she could be fallen in love with.

31. Of Isaac, who was born according to the promise, whose name was given on account of the laughter of both parents

After these things a son was born to Abraham, according to God's promise, of Sarah, and was called Isaac, which means laughter. For his father had laughed when he was promised to him, in wondering delight, and his mother, when he was again promised by those three men, had laughed, doubting for joy; yet she was blamed by the angel because that laughter, although it was for joy, yet was not full of faith. Afterwards she was confirmed in faith by the same angel. From this, then, the boy got his name. For when Isaac was born and called by that name, Sarah showed that her laughter was not that of scornful reproach, but that of joyful praise; for she said, "God hath made me to laugh, so that every one who hears will laugh with me."301 Then in a little while the bond maid was cast out of the house with her son; and, according to the apostle, these two women signify the old and new covenants, – Sarah representing that of the Jerusalem which is above, that is, the city of God.302

32. Of Abraham's obedience and faith, which were proved by the offering up of his son in sacrifice; and of Sarah's death

Among other things, of which it would take too long time to mention the whole, Abraham was tempted about the offering up of his well-beloved son Isaac, to prove his pious obedience, and so make it known to the world, not to God. Now every temptation is not blameworthy; it may even be praiseworthy, because it furnishes probation. And, for the most part, the human mind cannot attain to self-knowledge otherwise than by making trial of its powers through temptation, by some kind of experimental and not merely verbal self-interrogation; when, if it has acknowledged the gift of God, it is pious, and is consolidated by stedfast grace and not puffed up by vain boasting. Of course Abraham could never believe that God delighted in human sacrifices; yet when the divine commandment thundered, it was to be obeyed, not disputed. Yet Abraham is worthy of praise, because he all along believed that his son, on being offered up, would rise again; for God had said to him, when he was unwilling to fulfil his wife's pleasure by casting out the bond maid and her son, "In Isaac shall thy seed be called." No doubt He then goes on to say, "And as for the son of this bond woman, I will make him a great nation, because he is thy seed."303 How then is it said, "In Isaac shall thy seed be called," when God calls Ishmael also his seed? The apostle, in explaining this, says, "In Isaac shall thy seed be called, that is, they which are the children of the flesh, these are not the children of God: but the children of the promise are counted for the seed."304 In order, then, that the children of the promise may be the seed of Abraham, they are called in Isaac, that is, are gathered together in Christ by the call of grace. Therefore the father, holding fast from the first the promise which behoved to be fulfilled through this son whom God had ordered him to slay, did not doubt that he whom he once thought it hopeless he should ever receive would be restored to him when he had offered him up. It is in this way the passage in the Epistle to the Hebrews is also to be understood and explained. "By faith," he says, "Abraham overcame, when tempted about Isaac: and he who had received the promise offered up his only son, to whom it was said, In Isaac shall thy seed be called: thinking that God was able to raise him up, even from the dead;" therefore he has added, "from whence also he received him in a similitude."305 In whose similitude but His of whom the apostle says, "He that spared not His own Son, but delivered Him up for us all?"306 And on this account Isaac also himself carried to the place of sacrifice the wood on which he was to be offered up, just as the Lord Himself carried His own cross. Finally, since Isaac was not to be slain, after his father was forbidden to smite him, who was that ram by the offering of which that sacrifice was completed with typical blood? For when Abraham saw him, he was caught by the horns in a thicket. What, then, did he represent but Jesus, who, before He was offered up, was crowned with thorns by the Jews?

But let us rather hear the divine words spoken through the angel. For the Scripture says, "And Abraham stretched forth his hand to take the knife, that he might slay his son. And the Angel of the Lord called unto him from heaven, and said, Abraham. And he said, Here am I. And he said, Lay not thine hand upon the lad, neither do thou anything unto him: for now I know that thou fearest God, and hast not spared thy beloved son for my sake."307 It is said, "Now I know," that is, Now I have made to be known; for God was not previously ignorant of this. Then, having offered up that ram instead of Isaac his son, "Abraham," as we read, "called the name of that place The Lord seeth: as they say this day, In the mount the Lord hath appeared."308 As it is said, "Now I know," for Now I have made to be known, so here, "The Lord sees," for The Lord hath appeared, that is, made Himself to be seen. "And the Angel of the Lord called unto Abraham from heaven the second time, saying, By myself have I sworn, saith the Lord; because thou hast done this thing, and hast not spared thy beloved son for my sake; that in blessing I will bless thee, and in multiplying I will multiply thy seed as the stars of heaven, and as the sand which is upon the sea-shore; and thy seed shall possess by inheritance the cities of the adversaries: and in thy seed shall all the nations of the earth be blessed; because thou hast obeyed my voice."309 In this manner is that promise concerning the calling of the nations in the seed of Abraham confirmed even by the oath of God, after that burnt-offering which typified Christ. For He had often promised, but never sworn. And what is the oath of God, the true and faithful, but a confirmation of the promise, and a certain reproof to the unbelieving?

After these things Sarah died, in the 127th year of her life, and the 137th of her husband; for he was ten years older than she, as he himself says, when a son is promised to him by her: "Shall a son be born to me that am an hundred years old? and shall Sarah, that is ninety years old, bear?"310 Then Abraham bought a field, in which he buried his wife. And then, according to Stephen's account, he was settled in that land, entering then on actual possession of it, – that is, after the death of his father, who is inferred to have died two years before.

33. Of Rebecca, the grand-daughter of Nahor, whom Isaac took to wife

Isaac married Rebecca, the grand-daughter of Nahor, his father's brother, when he was forty years old, that is, in the 140th year of his father's life, three years after his mother's death. Now when a servant was sent to Mesopotamia by his father to fetch her, and when Abraham said to that servant, "Put thy hand under my thigh, and I will make thee swear by the Lord, the God of heaven, and the Lord of the earth, that thou shalt not take a wife unto my son Isaac of the daughters of the Canaanites,"311 what else was pointed out by this, but that the Lord, the God of heaven, and the Lord of the earth, was to come in the flesh which was to be derived from that thigh? Are these small tokens of the foretold truth which we see fulfilled in Christ?

34. What is meant by Abraham's marrying Keturah after Sarah's death

What did Abraham mean by marrying Keturah after Sarah's death? Far be it from us to suspect him of incontinence, especially when he had reached such an age and such sanctity of faith. Or was he still seeking to beget children, though he held fast, with most approved faith, the promise of God that his children should be multiplied out of Isaac as the stars of heaven and the dust of the earth? And yet, if Hagar and Ishmael, as the apostle teaches us, signified the carnal people of the old covenant, why may not Keturah and her sons also signify the carnal people who think they belong to the new covenant? For both are called both the wives and the concubines of Abraham; but Sarah is never called a concubine (but only a wife). For when Hagar is given to Abraham, it is written, "And Sarai, Abram's wife, took Hagar the Egyptian, her handmaid, after Abram had dwelt ten years in the land of Canaan, and gave her to her husband Abram to be his wife."312 And of Keturah, whom he took after Sarah's departure, we read, "Then again Abraham took a wife, whose name was Keturah."313 Lo, both are called wives, yet both are found to have been concubines; for the Scripture afterward says, "And Abraham gave his whole estate unto Isaac his son. But unto the sons of his concubines Abraham gave gifts, and sent them away from his son Isaac, (while he yet lived,) eastward, unto the east country."314 Therefore the sons of the concubines, that is, the heretics and the carnal Jews, have some gifts, but do not attain the promised kingdom; "For they which are the children of the flesh, these are not the children of God: but the children of the promise are counted for the seed, of whom it was said, In Isaac shall thy seed be called."315 For I do not see why Keturah, who was married after the wife's death, should be called a concubine, except on account of this mystery. But if any one is unwilling to put such meanings on these things, he need not calumniate Abraham. For what if even this was provided against the heretics who were to be the opponents of second marriages, so that it might be shown that it was no sin in the case of the father of many nations himself, when, after his wife's death, he married again? And Abraham died when he was 175 years old, so that he left his son Isaac seventy-five years old, having begotten him when 100 years old.

35. What was indicated by the divine answer about the twins still shut up in the womb of Rebecca their mother

Let us now see how the times of the city of God run on from this point among Abraham's descendants. In the time from the first year of Isaac's life to the seventieth, when his sons were born, the only memorable thing is, that when he prayed God that his wife, who was barren, might bear, and the Lord granted what he sought, and she conceived, the twins leapt while still enclosed in her womb. And when she was troubled by this struggle, and inquired of the Lord, she received this answer: "Two nations are in thy womb, and two manner of people shall be separated from thy bowels; and the one people shall overcome the other people, and the elder shall serve the younger."316 The Apostle Paul would have us understand this as a great instance of grace;317 for the children being not yet born, neither having done any good or evil, the younger is chosen without any good desert, and the elder is rejected, when beyond doubt, as regards original sin, both were alike, and as regards actual sin, neither had any. But the plan of the work on hand does not permit me to speak more fully of this matter now, and I have said much about it in other works. Only that saying, "The elder shall serve the younger," is understood by our writers, almost without exception, to mean that the elder people, the Jews, shall serve the younger people, the Christians. And truly, although this might seem to be fulfilled in the Idumean nation, which was born of the elder (who had two names, being called both Esau and Edom, whence the name Idumeans), because it was afterwards to be overcome by the people which sprang from the younger, that is, by the Israelites, and was to become subject to them; yet it is more suitable to believe that, when it was said, "The one people shall overcome the other people, and the elder shall serve the younger," that prophecy meant some greater thing; and what is that except what is evidently fulfilled in the Jews and Christians?

36. Of the oracle and blessing which Isaac received, just as his father did, being beloved for his sake

Isaac also received such an oracle as his father had often received. Of this oracle it is thus written: "And there was a famine over the land, beside the first famine that was in the days of Abraham. And Isaac went unto Abimelech king of the Philistines unto Gerar. And the Lord appeared unto him, and said, Go not down into Egypt; but dwell in the land which I shall tell thee of. And abide in this land, and I will be with thee, and will bless thee: unto thee and unto thy seed I will give all this land; and I will establish mine oath, which I sware unto Abraham thy father: and I will multiply thy seed as the stars of heaven, and will give unto thy seed all this land: and in thy seed shall all the nations of the earth be blessed; because that Abraham thy father obeyed my voice, and kept my precepts, my commandments, my righteousness, and my laws."318 This patriarch neither had another wife, nor any concubine, but was content with the twin-children begotten by one act of generation. He also was afraid, when he lived among strangers, of being brought into danger owing to the beauty of his wife, and did like his father in calling her his sister, and not telling that she was his wife; for she was his near blood-relation by the father's and mother's side. She also remained untouched by the strangers, when it was known she was his wife. Yet we ought not to prefer him to his father because he knew no woman besides his one wife. For beyond doubt the merits of his father's faith and obedience were greater, inasmuch as God says it is for his sake He does Isaac good: "In thy seed," He says, "shall all the nations of the earth be blessed, because that Abraham thy father obeyed my voice, and kept my precepts, my commandments, my statutes, and my laws." And again in another oracle He says, "I am the God of Abraham thy father: fear not, for I am with thee, and will bless thee, and multiply thy seed for my servant Abraham's sake."319 So that we must understand how chastely Abraham acted, because imprudent men, who seek some support for their own wickedness in the Holy Scriptures, think he acted through lust. We may also learn this, not to compare men by single good things, but to consider everything in each; for it may happen that one man has something in his life and character in which he excels another, and it may be far more excellent than that in which the other excels him. And thus, according to sound and true judgment, while continence is preferable to marriage, yet a believing married man is better than a continent unbeliever; for the unbeliever is not only less praiseworthy, but is even highly detestable. We must conclude, then, that both are good; yet so as to hold that the married man who is most faithful and most obedient is certainly better than the continent man whose faith and obedience are less. But if equal in other things, who would hesitate to prefer the continent man to the married?

37. Of the things mystically prefigured in Esau and Jacob

Isaac's two sons, Esau and Jacob, grew up together. The primacy of the elder was transferred to the younger by a bargain and agreement between them, when the elder immoderately lusted after the lentiles the younger had prepared for food, and for that price sold his birthright to him, confirming it with an oath. We learn from this that a person is to be blamed, not for the kind of food he eats, but for immoderate greed. Isaac grew old, and old age deprived him of his eyesight. He wished to bless the elder son, and instead of the elder, who was hairy, unwittingly blessed the younger, who put himself under his father's hands, having covered himself with kid-skins, as if bearing the sins of others. Lest we should think this guile of Jacob's was fraudulent guile, instead of seeking in it the mystery of a great thing, the Scripture has predicted in the words just before, "Esau was a cunning hunter, a man of the field; and Jacob was a simple man, dwelling at home."320 Some of our writers have interpreted this, "without guile." But whether the Greek ἄπλαστος means "without guile," or "simple," or rather "without feigning," in the receiving of that blessing what is the guile of the man without guile? What is the guile of the simple, what the fiction of the man who does not lie, but a profound mystery of the truth? But what is the blessing itself? "See," he says, "the smell of my son is as the smell of a full field which the Lord hath blessed: therefore God give thee of the dew of heaven, and of the fruitfulness of the earth, and plenty of corn and wine: let nations serve thee, and princes adore thee: and be lord of thy brethren, and let thy father's sons adore thee: cursed be he that curseth thee, and blessed be he that blesseth thee."321 The blessing of Jacob is therefore a proclamation of Christ to all nations. It is this which has come to pass, and is now being fulfilled. Isaac is the law and the prophecy: even by the mouth of the Jews Christ is blessed by prophecy as by one who knows not, because it is itself not understood. The world like a field is filled with the odour of Christ's name: His is the blessing of the dew of heaven, that is, of the showers of divine words; and of the fruitfulness of the earth, that is, of the gathering together of the peoples: His is the plenty of corn and wine, that is, the multitude that gathers bread and wine in the sacrament of His body and blood. Him the nations serve, Him princes adore. He is the Lord of His brethren, because His people rules over the Jews. Him His Father's sons adore, that is, the sons of Abraham according to faith; for He Himself is the son of Abraham according to the flesh. He is cursed that curseth Him, and he that blesseth Him is blessed. Christ, I say, who is ours is blessed, that is, truly spoken of out of the mouths of the Jews, when, although erring, they yet sing the law and the prophets, and think they are blessing another for whom they erringly hope. So, when the elder son claims the promised blessing, Isaac is greatly afraid, and wonders when he knows that he has blessed one instead of the other, and demands who he is; yet he does not complain that he has been deceived, yea, when the great mystery is revealed to him, in his secret heart he at once eschews anger, and confirms the blessing. "Who then," he says, "hath hunted me venison, and brought it me, and I have eaten of all before thou camest, and have blessed him, and he shall be blessed?"322 Who would not rather have expected the curse of an angry man here, if these things had been done in an earthly manner, and not by inspiration from above? O things done, yet done prophetically; on the earth, yet celestially; by men, yet divinely! If everything that is fertile of so great mysteries should be examined carefully, many volumes would be filled; but the moderate compass fixed for this work compels us to hasten to other things.
