2 Chronicles 21:1-4

Jehoshaphat died and was buried with his ancestors in Jerusalem, the city of David. Then his son Jehoram became king in his place. Jehoram’s brothers were Azariah, Jehiel, Zechariah, Azariahu, Michael, and Shephatiah. They were the sons of Jehoshaphat king of Judah. Jehoshaphat gave his sons many gifts of silver, gold, and valuable things, and he gave them strong, walled cities in Judah. But Jehoshaphat gave the kingdom to Jehoram, because he was the first son. When Jehoram took control of his father’s kingdom, he killed all his brothers with a sword and also killed some of the leaders of Judah.
