Genesis 40:1-4

Then it came about after these things, that the cupbearer and the baker for the king of Egypt offended their lord, the king of Egypt.

And Pharaoh was furious with his two officials, the chief cupbearer and the chief baker.

So he put them in confinement in the house of the captain of the bodyguard, in the prison, the same place where Joseph was imprisoned.

And the captain of the bodyguard put Joseph in charge of them, and he took care of them; and they were in confinement for some time.
