Genesis 39:20-23

So Joseph’s master took him and threw him into prison, the place where the king’s prisoners are confined, and he was left there. But YAHWEH was with Joseph and demonstrated to him his faithful love by giving him great favor in the sight of the warden. The warden put all the prisoners under Joseph’s care; he was placed in charge of all the prisoners and everything in the prison. The warden had no worries about the prison with Joseph in charge, because YAHWEH’s presence was with Joseph and caused everything Joseph did to prosper.
