Cup-bearer
   an officer of high rank with Egyptian, Persian, Assyrian, and
   Jewish monarchs. The cup-bearer of the king of Egypt is
   mentioned in connection with Joseph's history (Gen. 40:1-21;
   41:9). Rabshakeh (q.v.) was cup-bearer in the Assyrian court (2
   Kings 18:17). Nehemiah filled this office to the king of Persia
   (Neh. 1:11). We read also of Solomon's cup-bearers (1 Kings
   10:5; 2 Chr. 9:4).
