On Drunkenness

[210] The weak-willed incontinent soul has three servants who provide its feasts, the chief baker, the chief butler and the chief cook, whom our most admirable Moses mentions in these words, “And Pharaoh was wroth with his two eunuchs, with the chief butler and the chief baker, and he put them in prison under the chief gaoler” (Gen. 40:2, 3). But the chief cook is also a eunuch, for we have in another place, “and Joseph was brought down into Egypt and became the property of the eunuch of Pharaoh, the chief cook” (Gen. 39:1), and again “they sold Joseph to the eunuch of Pharaoh, the chief cook” (Gen. 37:36).
