Jehoash was 7 years old when he ascended to the throne, reigning for 40 years. (2 Kings 12:1, 2 Chronicles 24:1) He was succeeded by his son, Amaziah of Judah. He is said to have been righteous "all the days of Jehoiada the priest" but to have deviated from fidelity to Yahweh after Jehoiada's death .
