24. Of the meaning of the sacrifice Abraham was commanded to offer when he supplicated to be taught about those things he had believed.
In the same vision, God in speaking to him also says, "I am God that brought thee out of the region of the Chaldees, to give thee this land to inherit it."[273] And when Abram asked whereby he might know that he should inherit it, God said to him, "Take me an heifer of three years old, and a she-goat of three years old, and a ram of three years old, and a turtle-dove, and a pigeon. And he took unto him all these, and divided them in the midst, and laid each piece one against another; but the birds divided he not. And the fowls came down," as it is written, "on the carcases, and Abram sat down by them. But about the going down of the sun, great fear fell upon Abram; and, lo, an horror of great darkness fell upon him. And He said unto Abram, Know of a surety that thy seed shall be a stranger in a land not theirs, and they shall reduce them to servitude; and shall afflict them four hundred years: but the nation whom they shall serve will I judge; and afterward shall they come out hither with great substance. And thou shalt go to thy fathers in peace; kept in a good old age. But in the fourth generation they shall come hither again: for the iniquity of the Amorites is not yet full. And when the sun was setting, there was a flame, and a smoking furnace, and lamps of fire, that passed through between those pieces. In that day the Lord made a covenant with Abram, saying, Unto thy seed will I give this land, from the river of Egypt unto the great river Euphrates: the Kenites, and the Kenizzites, and the Kadmonites, and the Hittites, and the Perizzites, and the Rephaims, and the Amorites, and the Canaanites, and the Hivites, and the Girgashites, and the Jebusites."[274]
All these things were said and done in a vision from God; but it would take long, and would exceed the scope of this work, to treat of them exactly in detail. It is enough that we should know that, after it was said Abram believed in God, and it was counted to him for righteousness, he did not fail in faith in saying, "Lord God, whereby shall I know that I shall inherit it?" for the inheritance of that land was promised to him. Now he does not say, How shall I know, as if he did not yet believe; but he says, "Whereby shall I know," meaning that some sign might be given by which he might know the manner of those things which he had believed, just as it is not for lack of faith the Virgin Mary says, "How shall this be, seeing I know not a man?"[275] for she inquired as to the way in which that should take place which she was certain would come to pass. And when she asked this, she was told, "The Holy Ghost shall come upon thee, and the power of the Highest shall overshadow thee."[276] Here also, in fine, a symbol was given, consisting of three animals, a heifer, a she-goat, and a ram, and two birds, a turtle-dove and pigeon, that he might know that the things which he had not doubted should come to pass were to happen in accordance with this symbol. Whether, therefore, the heifer was a sign that the people should be put under the law, the she-goat that the same people was to become sinful, the ram that they should reign (and these animals are said to be of three years old for this reason, that there are three remarkable divisions of time, from Adam to Noah, and from him to Abraham, and from him to David, who, on the rejection of Saul, was first established by the will of the Lord in the kingdom of the Israelite nation: in this third division, which extends from Abraham to David, that people grew up as if passing through the third age of life), or whether they had some other more suitable meaning, still I have no doubt whatever that spiritual things were prefigured by them as well as by the turtle-dove and pigeon. And it is said, "But the birds divided he not," because carnal men are divided among themselves, but the spiritual not at all, whether they seclude themselves from the busy conversation of men, like the turtle-dove, or dwell among them, like the pigeon; for both birds are simple and harmless, signifying that even in the Israelite people, to which that land was to be given, there would be individuals who were children of the promise, and heirs of the kingdom that is[277] to remain in eternal felicity. But the fowls coming down on the divided carcases represent nothing good, but the spirits of this air, seeking some food for themselves in the division of carnal men. But that Abraham sat down with them, signifies that even amid these divisions of the carnal, true believers shall persevere to the end. And that about the going down of the sun great fear fell upon Abraham and a horror of great darkness, signifies that about the end of this world believers shall be in great perturbation and tribulation, of which the Lord said in the gospel, "For then shall be great tribulation, such as was not from the beginning."[278]
But what is said to Abraham, "Know of a surety that thy seed shall be a stranger in a land not theirs, and they shall reduce them to servitude, and shall afflict them 400 years," is most clearly a prophecy about the people of Israel which was to be in servitude in Egypt. Not that this people was to be in that servitude under the oppressive Egyptians for 400 years, but it is foretold that this should take place in the course of those 400 years. For as it is written of Terah the father of Abraham, "And the days of Terah in Haran were 205 years,"[279] not because they were all spent there, but because they were completed there, so it is said here also, "And they shall reduce them to servitude, and shall afflict them 400 years," for this reason, because that number was completed, not because it was all spent in that affliction. The years are said to be 400 in round numbers, although they were a little more,—whether you reckon from this time, when these things were promised to Abraham, or from the birth of Isaac, as the seed of Abraham, of which these things are predicted. For, as we have already said above, from the seventy-fifth year of Abraham, when the first promise was made to him, down to the exodus of Israel from Egypt, there are reckoned 430 years, which the apostle thus mentions: "And this I say, that the covenant confirmed by God, the law, which was made 430 years after, cannot disannul, that it should make the promise of none effect."[280] So then these 430 years might be called 400, because they are not much more, especially since part even of that number had already gone by when these things were shown and said to Abraham in vision, or when Isaac was born in his father's 100th year, twenty-five years after the first promise, when of these 430 years there now remained 405, which God was pleased to call 400. No one will doubt that the other things which follow in the prophetic words of God pertain to the people of Israel.
When it is added, "And when the sun was now setting there was a flame, and lo, a smoking furnace, and lamps of fire, which passed through between those pieces," this signifies that at the end of the world the carnal shall be judged by fire. For just as the affliction of the city of God, such as never was before, which is expected to take place under Antichrist, was signified by Abraham's horror of great darkness about the going down of the sun, that is, when the end of the world draws nigh,—so at the going down of the sun, that is, at the very end of the world, there is signified by that fire the day of judgment, which separates the carnal who are to be saved by fire from those who are to be condemned in the fire. And then the covenant made with Abraham particularly sets forth the land of Canaan, and names eleven tribes in it from the river of Egypt even to the great river Euphrates. It is not then from the great river of Egypt, that is, the Nile, but from a small one which separates Egypt from Palestine, where the city of Rhinocorura is.
25. Of Sarah's handmaid, Hagar, whom she herself wished to be Abraham's concubine.
And here follow the times of Abraham's sons, the one by Hagar the bond maid, the other by Sarah the free woman, about whom we have already spoken in the previous book. As regards this transaction, Abraham is in no way to be branded as guilty concerning this concubine, for he used her for the begetting of progeny, not for the gratification of lust; and not to insult, but rather to obey his wife, who supposed it would be a solace of her barrenness if she could make use of the fruitful womb of her handmaid to supply the defect of her own nature, and by that law of which the apostle says, "Likewise also the husband hath not power of his own body, but the wife,"[281] could, as a wife, make use of him for childbearing by another, when she could not do so in her own person. Here there is no wanton lust, no filthy lewdness. The handmaid is delivered to the husband by the wife for the sake of progeny, and is received by the husband for the sake of progeny, each seeking, not guilty excess, but natural fruit. And when the pregnant bond woman despised her barren mistress, and Sarah, with womanly jealousy, rather laid the blame of this on her husband, even then Abraham showed that he was not a slavish lover, but a free begetter of children, and that in using Hagar he had guarded the chastity of Sarah his wife, and had gratified her will and not his own,—had received her without seeking, had gone in to her without being attached, had impregnated without loving her,—for he says, "Behold thy maid is in thy hands: do to her as it pleaseth thee;"[282] a man able to use women as a man should,—his wife temperately, his handmaid compliantly, neither intemperately!
26. Of God's attestation to Abraham, by which He assures him, when now old, of a son by the barren Sarah, and appoints him the father of the nations, and seals his faith in the promise by the sacrament of circumcision.
After these things Ishmael was born of Hagar; and Abraham might think that in him was fulfilled what God had promised him, saying, when he wished to adopt his home-born servant, "This shall not be thine heir; but he that shall come forth of thee, he shall be thine heir."[283] Therefore, lest he should think that what was promised was fulfilled in the handmaid's son, "when Abram was ninety years old and nine, God appeared to him, and said unto him, I am God; be well-pleasing in my sight, and be without complaint, and I will make my covenant between me and thee, and will fill thee exceedingly."[284]
Here there are more distinct promises about the calling of the nations in Isaac, that is, in the son of the promise, by which grace is signified, and not nature; for the son is promised from an old man and a barren old woman. For although God effects even the natural course of procreation, yet where the agency of God is manifest, through the decay or failure of nature, grace is more plainly discerned. And because this was to be brought about, not by generation, but by regeneration, circumcision was enjoined now, when a son was promised of Sarah. And by ordering all, not only sons, but also home-born and purchased servants to be circumcised, he testifies that this grace pertains to all. For what else does circumcision signify than a nature renewed on the putting off of the old? And what else does the eighth day mean than Christ, who rose again when the week was completed, that is, after the Sabbath? The very names of the parents are changed: all things proclaim newness, and the new covenant is shadowed forth in the old. For what does the term old covenant imply but the concealing of the new? And what does the term new covenant imply but the revealing of the old? The laughter of Abraham is the exultation of one who rejoices, not the scornful laughter of one who mistrusts. And those words of his in his heart, "Shall a son be born to me that am an hundred years old? and shall Sarah, that is ninety years old, bear?" are not the words of doubt, but of wonder. And when it is said, "And I will give to thee, and to thy seed after thee, the land in which thou art a stranger, all the land of Canaan, for an everlasting possession," if it troubles any one whether this is to be held as fulfilled, or whether its fulfilment may still be looked for, since no kind of earthly possession can be everlasting for any nation whatever, let him know that the word translated everlasting by our writers is what the Greeks term αἰώνιον, which is derived from αἰὼν, the Greek for sæculum, an age. But the Latins have not ventured to translate this by secular, lest they should change the meaning into something widely different. For many things are called secular which so happen in this world as to pass away even in a short time; but what is termed αἰώνιον either has no end, or lasts to the very end of this world.
