When Jehu came to Samaria, he killed all of Ahab’s family in Samaria. He destroyed all those who were left, just as the Lord had told Elijah it would happen.
So Ahaziah died, just as the Lord, through Elijah, had said he would. Joram became king in Ahaziah’s place during the second year Jehoram son of Jehoshaphat was king of Judah. Joram ruled because Ahaziah had no son to take his place.
While Jehu was punishing Ahab’s family, he found the leaders of Judah and the sons of Ahaziah’s relatives who served Ahaziah, and Jehu killed them all.
“There is a day coming that will burn like a hot furnace, and all the proud and evil people will be like straw. On that day they will be completely burned up so that not a root or branch will be left,” says the Lord All-Powerful.
