Chemosh - the destroyer, subduer, or fish-god, the god of the Moabites (Num. 21:29; Jer. 48:7, 13, 46). The worship of this god, "the abomination of Moab," was introduced at Jerusalem by Solomon (1 Kings 11:7), but was abolished by Josiah (2 Kings 23:13). On the "Moabite Stone" (q.v.), Mesha (2 Kings 3:5) ascribes his victories over the king of Israel to this god, "And Chemosh drove him before my sight."
