Genesis 39:6-10

Thus he left all that he had in Joseph’s hand, and he did not know what he had except for the bread which he ate. Now Joseph was handsome in form and appearance. And it came to pass after these things that his master’s wife cast longing eyes on Joseph, and she said, “Lie with me.” But he refused and said to his master’s wife, “Look, my master does not know what is with me in the house, and he has committed all that he has to my hand. There is no one greater in this house than I, nor has he kept back anything from me but you, because you are his wife. How then can I do this great wickedness, and sin against God?” So it was, as she spoke to Joseph day by day, that he did not heed her, to lie with her or to be with her.
