“And here follow the times of Abraham's sons, the one by Hagar the bondmaid, 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 dealt with 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 solace of her barrenness if she could make use of the fruitful womb of her handmaid to supply the defect of her own nature. By that law of which the apostle says, "Likewise also the husband has not power of his own body, but the wife," Sarah could, as a wife, do benefit to him through childbearing by another, when she could not do so in her own person. Here there is no wanton lust, no crude 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. Then the pregnant bondwoman despised her barren mistress, and Sarah, with womanly jealousy, rather laid the blame of this on her husband. Yet 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. He had received her without seeking her, gone in to her without being attached, impregnated without loving her. For he says, "Behold, your maid is in your power; do to her as you please." Here is a man able to treat different women as they require—his wife temperately, his handmaid compliantly, neither intemperately!”

“AND SARAI DEALT HARSHLY WITH HER, AND SHE FLED FROM BEFORE HER FACE. Our mother did transgress by this affliction, and Abraham also by his permitting her to do so. And so, G-d heard her [Hagar’s] affliction and gave her a son who would be a wild-ass of a man, to afflict the seed of Abraham and Sarah with all kinds of affliction.”

“But Abram said unto Sarai,.... In a meek, mild and gentle manner: behold, thy maid is in thine hand; though Hagar was Abram's secondary wife he still considers her as Sarai's maid, and as subject to her, and allows her to exercise authority over her; for he still retained the same love and affection for Sarai, his first and lawful wife, and showed the same respect he ever did, and supported her in her honour and dignity: do to her as it pleaseth thee: not giving her liberty to take away her life, nor even to use her cruelly, but to deal with her as a mistress might lawfully do with a servant, or however exercise that power which a first wife had over a second: perhaps Abram, in complaisance to Sarai, gave her too large a commission, and left it too much in her power to distress Hagar; and it might have been more correct to have heard both sides, and judged between them, and used his own authority, by reproving and correcting as he saw meet; had she been only Sarai's maid and not his wife, it would have been less exceptionable; however, for peace sake, he gave leave to Sarai to do as she would: and when Sarai dealt hardly with her; or afflicted her (m), not only with words but with blows, as some think, and unmercifully beat her, and laid hard service upon her she was not able to go through, especially in her circumstances; though it may be she only chastised her in such a manner as a mistress may chastise her maid, since the angel seems to approve of what she did, Gen 16:9; which her proud spirit not being able to bear: she fled from her face; which was set against her, and was full of wrath and fury: she deserted her service, quitted Abram's house though with child by him; unmindful of the various relations she stood in, which should have obliged her to have kept her place, and especially until she had made proper remonstrances of her ill usage, and could have no redress; but, unable to bear the treatment she met with, meditated a flight into her own country, Egypt, for by what follows it appears she steered her course that way; this flight of hers was agreeable to her name, for Hagar in the Arabic language signifies to "flee", hence the flight of Mahomet is called the Hegira.

“Sarah dealt hardly with her - תאנה teanneha, she afflicted her; the term implying stripes and hard usage, to bring down the body and humble the mind. If the slave was to blame in this business the mistress is not less liable to censure. She alone had brought her into those circumstances, in which it was natural for her to value herself beyond her mistress.”
