Genesis 39:7-9

Then after a time his master's wife cast her eyes upon Joseph, and she said, Lie with me. But he refused and said to his master's wife, See here, with me in the house my master has concern about nothing; he has put all that he has in my care. He is not greater in this house than I am; nor has he kept anything from me except you, for you are his wife. How then can I do this great evil and sin against God?
