Carl Friedrich Keil and Franz Delitzsch Old Testament Commentary

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.).
