The term denotes a person attached to a king’s household in connection with the king’s cup: an individual attendant, or members of an organized group under a ruler. In Genesis 40:13 the restored man gives Pharaoh’s cup into his hand, while Genesis 40:2 and Genesis 40:20 refer to the ruler over such attendants.

   The singular construct form identifies the king of Egypt’s attendant in Genesis 40:1, and Genesis 40:13 places that attendant in the action of giving Pharaoh’s cup into his hand after restoration. Plural forms in Genesis 40:2, Genesis 40:20, Genesis 40:21, and Genesis 41:9 occur in the title of a ruler over this group; in Genesis 40:21 the APB renders the restoration of that ruler and the giving of the cup to Pharaoh.

In the Anselm Project Bible: The APB commonly presents the person as “cupbearer” or “cupbearers,” and titles the group’s leader “ruler of the cupbearers” or “chief cupbearer.” In Genesis 40:21 it also uses “cupbearing”; these are translation-level presentations rather than definitions.
