And Jehovah was with Joseph, and extended mercy to him, and gave him favour in the eyes of the chief of the tower-house.

And the chief of the tower-house committed to Joseph's hand all the prisoners that were in the tower-house; and whatever they had to do there he did.

The chief of the tower-house looked not to anything under his hand, because Jehovah was with him; and what he did, Jehovah made it prosper.

and 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.

And they dreamed a dream, both of them in one night, each his dream, each according to the interpretation of his dream, the cup-bearer and the baker of the king of Egypt, who were imprisoned in the tower-house.
