Genesis 39:7-9

And after many days his mistress cast her eyes on Joseph, and said: Lie with me. But he, in no wise consenting to that wicked act, said to her: Behold, my master hath delivered all things to me, and knoweth not what he hath in his own house. Neither is there any thing which is not in my power, or that he hath not delivered to me, but thee, who art his wife: How then can I do this wicked thing, and sin against my God?
