Genesis 39:1-2, 8-9, 20-21

Now Joseph had been taken down to Egypt. And Potiphar, an officer of Pharaoh, captain of the guard, an Egyptian, bought him from the Ishmaelites who had taken him down there. The LORD was with Joseph, and he was a successful man; and he was in the house of his master the Egyptian.

But he refused and said to his master’s wife, “Look, my master does not know what is with me in the house, and he has committed all that he has to my hand. There is no one greater in this house than I, nor has he kept back anything from me but you, because you are his wife. How then can I do this great wickedness, and sin against God?”

Then Joseph’s master took him and put him into the prison, a place where the king’s prisoners were confined. And he was there in the prison. But the LORD was with Joseph and showed him mercy, and He gave him favor in the sight of the keeper of the prison.
