Jehu the son of Hanani the seer went out to meet him and said to King Jehoshaphat, “Should you help the ungodly and love those who hate the Lord and in doing so bring wrath from the Lord on yourself?

Now the rest of the acts of Jehoshaphat, from the first to the last, behold, they are written in the records of Jehu the son of Hanani, which are recorded in the Book of the Kings of Israel.

But the downfall of Ahaziah was ordained by God, in that he went to Joram (Jehoram). For when he arrived there he went out [as an ally] with Jehoram against Jehu the son of Nimshi, whom the Lord had anointed to destroy the house of Ahab.

It came about that when Jehu was executing judgment on the house of Ahab, he found the leaders of Judah and the sons of Ahaziah’s [murdered] brothers ministering to Ahaziah, and he killed them.

Jehu also searched for Ahaziah, who was hiding in Samaria; he was captured, brought to Jehu, and put to death. They buried him, for they said, “After all, he is the grandson of Jehoshaphat, who sought the Lord with all his heart.” So the house of Ahaziah had no one left to retain the power to rule over the kingdom.

Then Amaziah king of Judah took counsel and sent word to Joash the son of Jehoahaz the son of Jehu, king of Israel, saying, “Come [to battle], let us face each other.”
