2 Chronicles 22:7-8

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.
