Genesis 39:7

7.Lie with me (145) Moses only briefly touches upon the chief points, and the sum of the things he relates. For there is no doubt that this impure woman endeavored, by various arts, to allure the pious youth, and that she insinuated herself by indirect blandishments, before she broke forth to such a shameless kind of license. But Moses, omitting other things, shows that she had been pushed so far by base lust, as not to shrink from openly soliciting a connection with Joseph. Now as this filthiness is a signal proof that carnal lust acts from blind and furious impulses; so, in the person of Joseph, an admirable example of fidelity and continence is set before us. His fidelity and integrity appear in this, that he acknowledges himself to be the more strictly bound, the greater the power with which he is entrusted. Ingenuous and courageous men have this property, that the more is confided to them, the less they can bear to deceive: but it is a rare virtue for those who have the power of doing injury to cultivate honesty gratuitously. Wherefore Joseph is not undeservedly commended by Moses, for regarding the authority with which he was invested by his master, as a bridle to restrain him from transgressing the bounds of duty. Besides, he gives also a proof of his gratitude, in bringing forward the benefits received from his master, as a reason why he should not subject him to any disgrace. And truly hence arises at this day such confusion everywhere, that men are half brutal, because this sacred bond of mutual society is broken. All, indeed, confess, that if they have received any benefit from another, they are under obligation to him: one even reproaches another for his ingratitude; but there are few who sincerely follow the example of Joseph. Lest, however, he should seem to be restrained only by a regard to man, he also declares that the act would be offensive to God. And, indeed, nothing is more powerful to overcome temptation than the fear of God. But he designedly commends the generosity of his master, in order that the wicked woman may desist from her abandoned purpose. To the same point is the objection which he mentions, Neither hath he kept anything back from me but thee, because thou art his wife. Why does he say this, except that, by recalling the religious obligation of marriage, he may wound the corrupt mind of the woman, and may cure her of her insane passion? Therefore he not only strenuously strives to liberate himself from her wicked allurements; but, lest her lusts should prove indomitable, he proposes to her the best remedy. And we may know that the sanctity of marriage is here commended to us in the history of Joseph, whereby the Lord would declare himself to be the maintainer of matrimonial fidelity, so that none who violate another’s bed should escape his vengeance. For he is a surety between the man and his wife, and requires mutual chastity from each. Whence it follows that, besides the injury inflicted upon man, God himself is grievously wronged.
