Genesis 39:7-9

And it came to pass after these things, that his master's wife cast her eyes upon Joseph; and she said, Lie with me. But he refused, and said unto his master's wife, Behold, my master wotteth not what is with me in the house, and he hath committed all that he hath to my hand; there is none greater in this house than I; neither hath he kept back any thing from me but thee, because thou art his wife: how then can I do this great wickedness, and sin against God?
