Before his reign as king, Jehu functioned as a commander in the army of Ahab (2 Kings 9:5, 25) in the northern kingdom of Israel. Jehu was the son of Jehoshaphat, although he is more commonly mentioned as son of Nimshi, his grandfather, perhaps because Nimshi was more well-known. Jehu’s name, meaning “Yahweh is he,” portrays well his future, God-given task: to obliterate the house of Ahab along with the worship of Baal that pervaded Israel at the time.
