Didymus the Blind : The intelligent strategy of the patriarch did not fail. They did not seek to do him harm. Moreover, a way out of it presented itself so that the marriage of the holy man would not be violated, because the Egyptians did not fling themselves on the woman relinquished by him. But the officials, after having seen her, in order to obtain the gratitude of the king, presented her to him as a gift, and thus it happened that they treated Abraham well because of her.Abraham entered then into Egypt allegorically by adapting himself as one of the perfect to the imperfect in order to do good to them instead of holding on to virtue as a privilege, as has been said above, but in showing her to all as his sister, in humility, so that by contemplating her they might come to love her. But observe how it is said that the officials saw her. There are in fact in the ranks of the allegorically viewed Egyptians some men who are purer, who have a great capacity for perceiving virtue. And they not only perceived her, but they introduced her to their superior, that is, to the reason that governs them, and they praised her. — ON Genesis 228
