2 Kings 1:17 AMP

[17] So Ahaziah [the son of King Ahab] died in accordance with the word of the LORD which Elijah had spoken. And because he had no son, Jehoram [his younger brother] became king [of Israel, the northern kingdom] in his place in the second year of Jehoram the son of Jehoshaphat, king of Judah [the southern kingdom].
