Genesis 39:2-6

The 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. Now his master saw that the LORD was with him and that the LORD caused all that he did to prosper (succeed) in his hand. [Gen 21:22; 26:27, 28; 41:38, 39] So 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. It 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. So Potiphar left all that he owned in Joseph’s charge; and with Joseph there he did not [need to] pay attention to anything except the food he ate. N ow Joseph was handsome and attractive in form and appearance. [Gen 43:32]
