3. And God commended his virtue, and said, Thou shalt not however lose the rewards thou hast deserved to receive by such thy glorious actions. He answered, And what advantage will it be to me to have such rewards, when I have none to enjoy them after me?—for he was hitherto childless. And God promised that he should have a son, and that his posterity should be very numerous; insomuch that their number should be like the stars. When he heard that, he offered a sacrifice to God, as he commanded him. The manner of the sacrifice was this:—He took an heifer of three years old, and a she-goat of three years old, and a ram in like manner of three years old, and a turtle-dove, and a pigeon 19 and as he was enjoined, he divided the three former, but the birds he did not divide. After which, before he built his altar, where the birds of prey flew about, as desirous of blood, a Divine voice came to him, declaring that their neighbors would be grievous to his posterity, when they should be in Egypt, for four hundred years; 20 during which time they should be afflicted, but afterwards should overcome their enemies, should conquer the Canaanites in war, and possess themselves of their land, and of their cities. 4. Now Abram dwelt near the oak called Ogyges,—the place belongs to Canaan, not far from the city of Hebron. But being uneasy at his wife's barrenness, he entreated God to grant that he might have male issue; and God required of him to be of good courage, and said that he would add to all the rest of the benefits that he had bestowed upon him, ever since he led him out of Mesopotamia, the gift of children. Accordingly Sarai, at God's command, brought to his bed one of her handmaidens, a woman of Egyptian descent, in order to obtain children by her; and when this handmaid was with child, she triumphed, and ventured to affront Sarai, as if the dominion were to come to a son to be born of her. But when Abram resigned her into the hand of Sarai, to punish her, she contrived to fly away, as not able to bear the instances of Sarai's severity to her; and she entreated God to have compassion on her. Now a Divine Angel met her, as she was going forward in the wilderness, and bid her return to her master and mistress, for if she would submit to that wise advice, she would live better hereafter; for that the reason of her being in such a miserable case was this, that she had been ungrateful and arrogant towards her mistress. He also told her, that if she disobeyed God, and went on still in her way, she should perish; but if she would return back, she should become the mother of a son who should reign over that country. These admonitions she obeyed, and returned to her master and mistress, and obtained forgiveness. A little while afterwards, she bare Ismael; which may be interpreted Heard of God, because God had heard his mother's prayer.
