Genesis 40:9

The cup-bearer gave this account: "In my dream, behold there was a vine before me, and on the vine three branches; and it was as though blossoming, it shot forth its blossom (נצּהּ either from the hapax l. נץ = נצּה, or from נצּה with the fem. termination resolved into the 3 pers. suff.: Ewald, 257d), its clusters ripened into grapes. And Pharaoh's cup was in my hand; and I took the grapes and pressed them into Pharaoh's cup, and gave the cup into Pharaoh's hand." In this dream the office and duty of the royal cup-bearer were represented in an unmistakeable manner, though the particular details must not be so forced as to lead to the conclusion, that the kings of ancient Egypt drank only the fresh juice of the grape, and not fermented wine as well. The cultivation of the vine, and the making and drinking of wine, among the Egyptians, are established beyond question by ancient testimony and the earliest monuments, notwithstanding the statement of Herodotus (2, 77) to the contrary (see Hengstenberg, Egypt and the Books of Moses, pp. 13ff.).

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).

40:9-19 Joseph listened to the dreams and offered their interpretations. These dreams were not trivial; they were ominous warnings from God about what everyone was going to face. These two dreams prepared for Pharaoh’s two dreams, which revealed the periods of life and death that the nation would soon experience.
