He is said to have given himself up to a life of wickedness, introducing many heathen and idolatrous customs (Isa. 8:19; 38:8; 2 Kings 23:12). He ignored the remonstrances and warnings of the prophets Isaiah, Hosea, and Micah, and appealed to Tiglath-Pileser III, the king of Assyria, for help against Rezin, king of Damascus, and Pekah, king of Israel, who threatened Jerusalem, This brought a great injury of his kingdom, and his own humilating subjection to the Assyrians (2 Kings 16:7, 9; 15:29).
He died at the age of thirty-five years, after reigning sixteen years, and was succeeded by his son Hezekiah. Because of his wickedness he was "not brought into the sepulchre of the kings."
