1. Mose 40:18

The head cup-bearer and head baker had committed crimes against the king of Egypt, and were imprisoned in "the prison of the house of the captain of the trabantes, the prison where Joseph himself was confined;" the state-prison, according to Eastern custom, forming part of the same building as the dwelling-house of the chief of the executioners. From a regard to the exalted position of these two prisoners, Potiphar ordered Joseph to wait upon them, not to keep watch over them; for את פּקד does not mean to appoint as guard, but to place by the side of a person.

In this chapter things are working, though slowly, towards Joseph's advancement. I. Two of Pharaoh's servants are committed to prison, and there to Joseph's care, and so become witnesses of his extraordinary conduct (Gen 40:1-4). II. They dreamed each of them a dream, which Joseph interpreted (Gen 40:5-19), and the event verified the interpretation (Gen 40:20-22), and so they became witnesses of his extraordinary skill. III. Joseph recommends his case to one of them, whose preferment he foresaw (Gen 40:14, Gen 40:15), but in vain (Gen 40:23).
