Genesis 39:7-10

7After some time his master’s wife looked longingly at Joseph and said, “Sleep with me.”

8But he refused. “Look,” he said to his master’s wife, “with me here my master does not concern himself with anything in his house, and he has put all that he owns under my authority.

9No one in this house is greater than I am. He has withheld nothing from me except you, because you are his wife. So how could I do this immense evil, and how could I sin against God?”

10Although she spoke to Joseph day after day, he refused to go to bed with her.
