Psalms 105:16-22

Then he called down a famine on the country, he broke every last blade of wheat. But he sent a man on ahead: Joseph, sold as a slave. They put cruel chains on his ankles, an iron collar around his neck, Until God’s word came to the Pharaoh, and GOD confirmed his promise. God sent the king to release him. The Pharaoh set Joseph free; He appointed him master of his palace, put him in charge of all his business To personally instruct his princes and train his advisors in wisdom.
