Genesis 16:6

6.Behold, thy maid is in thy hand. The greatness of Abram’s humanity and modesty appears from his answer. He does not quarrel with his wife; and though he has the best cause, yet he does not pertinaciously defend it, but voluntarily dismisses the wife who had been given him. In short, for the sake of restoring peace, he does violence to his feelings, both as a husband, and a father. For, in leaving Hagar to the will of her enraged mistress, he does not treat her as his wife; he also, in a certain way, undervalues that object of his hope which was conceived in her womb. And it is not to be doubted that he was thus calm and placid in bearing the vehemence of his wife; because, throughout her whole life, he had found her to be obedient. Still it was a great excellence, to restrain his temper under an indignity so great. It may, however, here be asked, how it was that his care for the blessed seed had then vanished from his mind? Hagar is great with child; he hopes that the seed through which the salvation of the world was promised, is about to proceed from her. Why then does he not set Sarai aside, and turn his love and desire still more to Hagar? Truly we hence infer, that all human contrivances pass away and vanish in smoke, as soon as any grievous temptation is presented. Having taken a wife against the divine command, he thinks the matter is succeeding well, when he sees her pregnant, and pleases himself in foolish confidence; but when contention suddenly arises, he is at his wit’s end, and rejects all hope, or, at least, forgets it. The same thing must necessarily happen to us, as often as we attempt anything contrary to the word of God. Our minds will fail at the very first blast of temptation; (386) since our only ground of stability is, to have the authority of God for what we do. In the meantime, God purifies the faith of his servant from its rust; for by mixing his own and his wife’s imagination with the word of God, he, in a sense, had stifled his faith; wherefore, to restore its brightness, that which was superfluous is cut of. God, by opposing himself in this manner to our sinful designs, recalls us from our stupidity to a sound mind. A simple promise had been given ‘I will bless thy seed.’ Sarai’s gloss supervened, (387) namely, that she could have no seed but a supposititious one by Hagar: this mire of human imagination, with which the promise had been defiled must be purged away, that Abram might derive his knowledge from no other source, than the pure word of God.

And Sarai dealt hardly with her (388) The word ענה (anah,) which Moses uses, signifies to afflict and to humble. I therefore explain it as being put for reducing Hagar to submission. But it was difficult for an angry woman to keep within bounds, in repressing the insolence of her maid. Wherefore, it is possible that she became immoderately enraged against her; not so much considering her own duty as revolving the means of being avenged for the offenses committed. Since Moses brings no heavier charge, I confine myself to what is certain; that Sarai made use of her proper authority in restraining the insolence of her maid. And, doubtless, from the event, we may form a judgments that Hagar was impelled to flee, not so much by the cruelty of her mistress, as by her own contumacy. Her own conscience accused her; and it is improbable that Sarai should have been so greatly incensed, except by many, and, indeed atrocious offenses. Therefore, the woman being of servile temper, and of indomitable ferocity, chose rather to flee, than to return to favor, through the humble acknowledgment of her fault.
