Genesis 39:18

And Joseph was brought down to Egypt; and Potiphar, an officer of Pharaoh, captain of the guard, an Egyptian, bought him of the hands of the Ishmeelites, which had brought him down thither.

And the LORD 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 the LORD was with him, and that the LORD made all that he did to prosper in his hand.

And Joseph found grace in his sight, and he served him: and he made him overseer over his house, and all that he had he put into his hand.
