After Jehoiada's death, however, a contest arose between his son and successor Zachariah and the king, which cost the former his life. The details have not reached us; it has only been stated that at Joash's command some princes of Judah stoned the son of Jehoiada in the Temple courts, and that the young high priest, in his dying moments, exclaimed, "May God take account of this and avenge it!" In every other respect, the overthrow of the house of Omri, which had caused so many differences and quarrels in Samaria and Jerusalem, had resulted in the internal peace of both kingdoms. The present condition was tolerable, except that private altars still existed in the kingdom of Judah, and that the God of Israel was still worshipped under the form of a bull in the kingdom of the Ten Tribes. The worship of Baal was, however, banished from both kingdoms. From without, both lands were harassed by enemies. Jehu, the bold chief of horsemen, who had destroyed the house of Omri in Jezreel and Samaria, did not display the same energy against powerful foreign enemies. Hazael, the Aramæan regicide, who was daring in warlike undertakings and eager for conquest, attacked the land of Israel with his troops, took the citadels by storm, burnt the houses, and spared neither children nor women. He also conquered the towns on the other side of the Jordan. The entire district of Manasseh, Gad, and Reuben, from the mountains of Bashan to the Arnon, was snatched from the kingdom of the Ten Tribes. Many of the inhabitants were crushed to death under iron ploughshares; the survivors were reduced to a state of semi-bondage. Jehu was not in a position to hold his ground against Hazael, perhaps because he also met with opposition from the king of Tyre, whose relatives and allies he had slain. Matters fared still worse under his son Jehoahaz (859-845). The land had been so hard pressed by Hazael and his son Ben-hadad, and the Israelites had been so reduced in strength, that their available forces consisted of but 10,000 infantry, fifty horse-soldiers, and ten war-chariots. From time to time the Aramæans made inroads, carried off booty and captured prisoners, whom they treated and sold as slaves. Jehoahaz appears to have concluded a disgraceful peace with the conqueror, to whose troops he granted free passage through his lands. Thereupon Hazael overran the land of the Philistines with his warriors, and besieged and conquered the town of Gath. He then intended to advance against Jerusalem, but Joash submitted without a stroke and bought peace. Either popular discontent was aroused by his cowardice, or he had in other ways caused disaffection; at all events, several nobles of Judah conspired against him, and two of them, Jozachar and Jehozabad, killed him in a house where he chanced to be staying.
