Genesis 40:2-4

Young's Literal Translation

² and Pharaoh is wroth against his two eunuchs, against the chief of the butlers, and against the chief of the bakers,

³ and giveth them in charge in the house of the chief of the executioners, unto the round-house, the place where Joseph [is] a prisoner,

⁴ and the chief of the executioners chargeth Joseph with them, and he serveth them; and they are days in charge.
