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

Now Joseph had been taken down to Egypt. An Egyptian named Potiphar was an officer to the king of Egypt and the captain of the palace guard. He bought Joseph from the Ishmaelites who had brought him down there. The LORD was with Joseph, and he became a successful man. He lived in the house of his master, Potiphar the Egyptian.

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.”

So Potiphar arrested Joseph and put him into the prison where the king’s prisoners were put. And Joseph stayed there in the prison. But the LORD was with Joseph and showed him kindness and caused the prison warden to like Joseph.
