2 Chronicles 21:2-4

The Voice

² Jehoshaphat, king of the true Israel,^[a] had a number of sons in addition to Jehoram: Azariah, Jehiel, Zechariah, Azaryahu, Michael, and Shephatiah. ³ Jehoshaphat made each one a wealthy governor with silver, gold, and costly gifts over his own fortified cities in Judah and appointed Jehoram as the future king since he was the firstborn. ⁴ Once Jehoram had taken over his father’s kingdom and had established himself, he killed all his brothers and some rulers of Israel so they could not challenge his right to rule.
