Genesis 39:7-12

7and after some time his master’s wife cast her eyes upon 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 entrusted everything he owns to my care. 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 such a great evil and sin against God?”

10Although Potiphar’s wife spoke to Joseph day after day, he refused to go to bed with her or even be near her. 11One day, however, Joseph went into the house to attend to his work, and not a single household servant was inside. 12She grabbed Joseph by his cloak and said, “Sleep with me!” But leaving his cloak in her hand, he escaped and ran outside.
