Joash of Israel

King Joash of Israel began his reign in the thirty-seventh year of the reign of King Joash of Judah, so there was some overlap. King Amaziah started ruling Judah in the second year of King Joash of Israel. Amaziah of Judah battled against the Edomites and then challenged Joash of Israel to battle (2 Kings 14:7–8). Joash refused, essentially telling Amaziah he was needlessly stirring up trouble (2 Kings 14:9–10). Amaziah did not heed the warning, and Joash of Israel defeated Judah in battle. Second Chronicles 25:20 says that Judah’s defeat was “because they sought the gods of Edom.”

Second Kings records another of Joash of Israel’s military victories. When Joash’s father, Jehoahaz, was reigning, King Hazael of Aram (the same king that Joash of Judah had kept from attacking Jerusalem) oppressed Israel (2 Kings 13:22). “But the Lord was gracious to them and had compassion and showed concern for them because of his covenant with Abraham, Isaac and Jacob. To this day he has been unwilling to destroy them or banish them from his presence” (2 Kings 13:23). When the prophet Elisha was sick and near to death, King Joash of Israel visited the prophet, apparently disconcerted over the military situation in Israel (2 Kings 13:14). Elisha instructed Joash to shoot arrows out of the open window. The prophet then proclaimed, “The Lord’s arrow of victory, the arrow of victory over Aram! . . . You will completely destroy the Arameans at Aphek” (2 Kings 13:17). Elisha next instructed Joash to strike the ground with the arrows. Joash did so but stopped after three strikes. “The man of God was angry with him and said, ‘You should have struck the ground five or six times; then you would have defeated Aram and completely destroyed it. But now you will defeat it only three times’” (2 Kings 13:19). When Hazael died and his son, Ben-hadad, took over, Joash did defeat him three times. Israel was able to recover cities that previously had been taken from them (2 Kings 13:24–25).

King Joash of Israel ruled for sixteen years and “did evil in the eyes of the Lord and did not turn away from any of the sins of Jeroboam son of Nebat, which he had caused Israel to commit; he continued in them” (2 Kings 13:11). After he died, Joash of Israel was succeeded by his son Jeroboam II (2 Kings 14:16).
