Psalms 105:17-21

Then he sent someone to Egypt ahead of them— Joseph, who was sold as a slave. They bruised his feet with fetters and placed his neck in an iron collar. Until the time came to fulfill his dreams, the LORD tested Joseph’s character. Then Pharaoh sent for him and set him free; the ruler of the nation opened his prison door. Joseph was put in charge of all the king’s household; he became ruler over all the king’s possessions.
