God helped Joseph, so Pharaoh appointed him to govern Egypt.

Acts 7:9-10

9 “You know that Jacob’s older sons became jealous because their father favored their younger brother Joseph. So they sold him to merchants/traders who took him [MTY] to Egypt. There he became a slave of an official who lived there. But God helped Joseph. 10 He protected him whenever people caused him to suffer. He enabled Joseph to be wise; and he caused Pharaoh, the king of Egypt, to think well of Joseph. So Pharaoh appointed him to rule over Egypt and to look after all of Pharaoh’s property [MTY].”
