Genesis 39:1-4

When Joseph was taken to Egypt by the Ishmaelite traders, he was purchased by Potiphar, an Egyptian officer. Potiphar was captain of the guard for Pharaoh, the king of Egypt. The LORD was with Joseph, so he succeeded in everything he did as he served in the home of his Egyptian master. Potiphar noticed this and realized that the LORD was with Joseph, giving him success in everything he did. This pleased Potiphar, so he soon made Joseph his personal attendant. He put him in charge of his entire household and everything he owned.
