Rabshakeh (răb'ska-kçh or rab-shâ'keh). An officer—the chief butler or cupbearer—who was sent with Rab-saris, the chief of the eunuchs, and Tartan, messengers of the king of Assyria, to Hezekiah, summoning him, in the most indecent and blasphemous manner, to surrender his capital. 2 Kings 18:17-37.
