Genesis 39:7-10

After some time the wife of Joseph’s master began to desire Joseph, and one day she said to him, “Have sexual relations with me.” But Joseph refused and said to her, “My master trusts me with everything in his house. He has put me in charge of everything he owns. There is no one in his house greater than I. He has not kept anything from me except you, because you are his wife. How can I do such an evil thing? It is a sin against God.” The woman talked to Joseph every day, but he refused to have sexual relations with her or even spend time with her.
