God appeared again to Abraham at the oak of Mature 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 favor before thee,"(1) 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,"(2) 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,"(3) 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,"(4) etc. This makes it much more credible that both Abraham in the three men and Lot in the two recognized 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." 5 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."(6) And here these two things, are promised with the utmost brevity and fullness,--the nation of Israel according to the

flesh, and all nations according to faith.

CHAP. 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 for-bidding 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 savor 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 site, but not by the mother's;(7) 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.

CHAP. 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."(1) 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.(2)

CHAP. 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 blame-worthy; it may even be praise-worthy, 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 steadfast 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 fulfill 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."[3] 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."[4] 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."[5] In whose similitude but His of whom the apostle says, "He that spared not His own Son, but delivered Him up for us all?"(6) 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."(7) 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."(8) 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 seashore; 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."(1) 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?"(2) 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.

CHAP. 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,"(3) 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?

CHAP. 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 Abraham had dwelt ten years in the land of Canaan, and gave her to her husband Abram to be his wife."(4) And of Keturah, whom he took after Sarah's departure, we read, "Then again Abraham took a wife, whose name was Keturah."(5) 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."(6) 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."(7) 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.
