Babylon is compared to a cup, because she was the vessel in the hand of God, to make drunken with His vengeance the other peoples (Jer 13:12; Jer 25:15, Jer 25:16). Compare as to spiritual Babylon, Rev 14:8; Rev 17:4. The cup is termed “golden,” to express the splendor and opulence of Babylon; whence also in the image seen by Nebuchadnezzar (Dan 2:38) the head representing Babylon is of gold (compare Isa 14:4).
