Genesis 39:8

"Afterwards," it says. What is meant by "afterwards"? After Joseph had been entrusted with control of the whole household and after his being shown such esteem by his master, "his master's wife set her eye on Joseph." See the shamelessness of this wanton woman. It was not because she considered herself to be mistress of the house that she took this into her head; it was not because he was a servant. Instead, under the spell of Joseph's charm and aflame with satanic desire, she endeavored at this point to assail the young man. With this evil intent fixed in her mind, she looked for a suitable moment of privacy for putting into effect this illicit endeavor. "But he refused," the text says. He did not submit, nor did he accept the invitation. Joseph realized, you see, the great ruin it would bring him. Instead of thinking of himself, he was greatly concerned as well to deliver her from this folly and improper desire, as far as was possible. He offered her advice calculated to awaken her to a sense of shame and make her realize what was for her good.

But what should I say about the arrangement of his private house, which he governed? However, he accomplished more by ruling himself before others. And even though he was attractive in appearance and very handsome, he did not use the beauty of his face to cause harm to others, but preserved it for his own grace. He believed himself to be more beautiful if he could prove himself more attractive through modesty and the cultivation of chastity rather than through the loss of his virtue. He considered true beauty to be one that didn't attract the eyes of others or harm fragile minds, but gained the admiration and judgment of everyone, being of no deceit and deserving praise. Now, if anyone with impudent eyes looked, the fault is of the one who saw improperly, not of the one who did not want to be seen improperly; and there is no fault in what was seen. It was not in the power of the servant not to be seen: the husband should have guarded the eyes of his wife. If he had no fear about his wife, this man believed it to be a testimony of modesty, not a laxity of behavior. However, men should learn to even guard the eyes of women. For even those who do not want to be loved are attracted. Finally, Joseph was tempted by a woman who scorned his love. And Scripture defended him well, saying: "And his master's wife cast her eyes on Joseph"; that is, he did not display himself, nor did he take advantage. But she cast her own snares and was caught in her own trap. She spread her own nets and became entangled in her own chains.
