2 Chronicles 21:2-4

Evangelical Heritage Version

² Jehoram had brothers, who were the sons of Jehoshaphat. They were Azariah, Jehiel, Zechariah, Azariahu, Michael, and Shephatiah. All these were sons of Jehoshaphat king of Israel. ³ Their father gave them many gifts: silver, gold, and valuable possessions, as well as fortified cities in Judah, but he gave the kingship to Jehoram because he was the firstborn.

⁴ Jehoram ascended to the throne of his father and strengthened his position. Then he killed all his brothers with the sword and also killed some of the officials of Israel.
