Genesis 39:2-5

2The Lord was with Joseph, and he [even though a slave] became a successful and prosperous man; and he was in the house of his master, the Egyptian.

3Now his master saw that the Lord was with him and that the Lord caused all that he did to prosper (succeed) in his hand.

4So Joseph pleased Potiphar and found favor in his sight and he served him as his personal servant. He made Joseph overseer over his house, and he put all that he owned in Joseph’s charge.

5It happened that from the time that he made Joseph overseer in his house and [put him in charge] over all that he owned, that the Lord blessed the Egyptian’s house because of Joseph; so the Lord’s blessing was on everything that Potiphar owned, in the house and in the field.
