Genesis 39:1-3

And Joseph was brought down to Egypt; and Potiphar, an officer of Pharaoh’s, the captain of the guard, an Egyptian, bought him of the hand of the Ishmaelites, that had brought him down thither. And Jehovah was with Joseph, and he was a prosperous man; and he was in the house of his master the Egyptian. And his master saw that Jehovah was with him, and that Jehovah made all that he did to prosper in his hand.
