Genesis 40:4

2And Pharaoh was wroth against two of his officers, against the chief of the butlers, and against the chief of the bakers.

3And he put them in ward in the house of the captain of the guard, into the prison, the place where Joseph was bound.

4And the captain of the guard charged Joseph with them, and he served them: and they continued a season in ward.

5And they dreamed a dream both of them, each man his dream in one night, each man according to the interpretation of his dream, the butler and the baker of the king of Egypt, which were bound in the prison.

6And Joseph came in unto them in the morning, and looked upon them, and, behold, they were sad.
