Genesis 40:1-4

1And it came to pass after these things, [that] the cup-bearer of the king of Egypt and the baker offended their lord the king of Egypt.

2And Pharaoh was wroth with his two chamberlains — with the chief of the cup-bearers and with the chief of the bakers;

3and he put them in custody into the house of the captain of the life-guard, into the tower-house, into the place where Joseph was imprisoned.

4And the captain of the life-guard appointed Joseph to them, that he should attend on them. And they were [several] days in custody.
