Joseph had been taken to Egypt. Potiphar, one of Pharaoh's Egyptian officials and captain of the guard, bought him from the Ishmaelites who had taken him there.
The LORD was with Joseph, so he became a successful man. He worked in the house of his Egyptian master.
Joseph's master saw that the LORD was with him and that the LORD made everything he did successful.
Potiphar liked Joseph so much that he made him his trusted servant. He put him in charge of his household and everything he owned.
From that time on the LORD blessed the Egyptian's household because of Joseph. Therefore, the LORD's blessing was on everything Potiphar owned in his house and in his fields.
So he left all that he owned in Joseph's care. He wasn't concerned about anything except the food he ate. Joseph was well-built and handsome.
