2 Kings 8:18

Two and twenty years old was Ahaziah when he began to reign; and he reigned one year in Jerusalem. And his mother’s name was Athaliah, the daughter of Omri king of Israel.

And Jehu the son of Hanani the seer went out to meet him, and said to king Jehoshaphat, Shouldest thou help the ungodly, and love them that hate the LORD? therefore is wrath upon thee from before the LORD.

And he walked in the way of the kings of Israel, like as did the house of Ahab: for he had the daughter of Ahab to wife: and he wrought that which was evil in the eyes of the LORD.

But there was none like unto Ahab, which did sell himself to work wickedness in the sight of the LORD, whom Jezebel his wife stirred up.

For the statutes of Omri are kept, and all the works of the house of Ahab, and ye walk in their counsels; that I should make thee a desolation, and the inhabitants thereof an hissing: therefore ye shall bear the reproach of my people.

For he built up again the high places which Hezekiah his father had destroyed; and he reared up altars for Baal, and made a grove, as did Ahab king of Israel; and worshipped all the host of heaven, and served them.

But hast walked in the way of the kings of Israel, and hast made Judah and the inhabitants of Jerusalem to go a whoring, like to the whoredoms of the house of Ahab, and also hast slain thy brethren of thy father’s house, which were better than thyself:

And I will stretch over Jerusalem the line of Samaria, and the plummet of the house of Ahab: and I will wipe Jerusalem as a man wipeth a dish, wiping it, and turning it upside down.

Now Jehoshaphat had riches and honour in abundance, and joined affinity with Ahab.
