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).
