God watches over the righteous, when the wretched would do them harm.

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. Thus he left all that he had in Joseph’s hand, and he did not know what he had except for the bread which he ate. Now Joseph was handsome in form and appearance. And it came to pass after these things that his master’s wife cast longing eyes on Joseph, and she said, “Lie with me.” 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?” But it happened about this time, when Joseph went into the house to do his work, and none of the men of the house was inside, that she caught him by his garment, saying, “Lie with me.” But he left his garment in her hand, and fled and ran outside. So she kept his garment with her until his master came home. 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. The keeper of the prison did not look into anything that was under Joseph’s authority, because the Lord was with him; and whatever he did, the Lord made it prosper.
