2 Chronicles 21:1-4

Jehoshaphat died and was buried in the family cemetery in the City of David. Jehoram his son was the next king. Jehoram’s brothers were Azariah, Jehiel, Zechariah, Azariahu, Michael, and Shephatiah—the sons of Jehoshaphat king of Judah. Their father had lavished them with gifts—silver, gold, and other valuables, plus the fortress cities in Judah. But Jehoram was his firstborn son and he gave him the kingdom of Judah. But when Jehoram had taken over his father’s kingdom and had secured his position, he killed all his brothers along with some of the government officials.
