And the destruction of Ahaziah was of God by coming to Joram: for when he was come, he went out with Jehoram against Jehu the son of Nimshi, whom the LORD had anointed to cut off the house of Ahab.
God caused Ahaziah's destruction through his connection with Joram. When Ahaziah met Joram, they both fought alongside Jehoram against Jehu, who was anointed by the LORD to eliminate the family of Ahab.
