This verse gives the formal details and family connection of his reign.
25In the twelfth year of the reign of Joram son of Ahab over Israel, Ahaziah son of Jehoram became king of Judah. 26Ahaziah was twenty-two years old when he became king, and he reigned in Jerusalem one year. His mother’s name was Athaliah, the granddaughter of Omri king of Israel. 27And Ahaziah walked in the ways of the house of Ahab and did evil in the sight of the LORD like the house of Ahab, for he was a son-in-law of the house of Ahab. 28Then Ahaziah went with Joram son of Ahab to fight against Hazael king of Aram at Ramoth-gilead, and the Arameans wounded Joram. 29So King Joram returned to Jezreel to recover from the wounds that the Arameans had inflicted on him at Ramah when he fought against Hazael king of Aram. Then Ahaziah son of Jehoram king of Judah went down to Jezreel to visit Joram son of Ahab, because Joram had been wounded.
