Genesis 39:6-12

So Potiphar gave Joseph complete administrative responsibility over everything he owned. With Joseph there, he didn’t worry about a thing—except what kind of food to eat! Joseph was a very handsome and well-built young man, and Potiphar’s wife soon began to look at him lustfully. “Come and sleep with me,” she demanded. But Joseph refused. “Look,” he told her, “my master trusts me with everything in his entire household. No one here has more authority than I do. He has held back nothing from me except you, because you are his wife. How could I do such a wicked thing? It would be a great sin against God.” She kept putting pressure on Joseph day after day, but he refused to sleep with her, and he kept out of her way as much as possible. One day, however, no one else was around when he went in to do his work. She came and grabbed him by his cloak, demanding, “Come on, sleep with me!” Joseph tore himself away, but he left his cloak in her hand as he ran from the house.
