2 Chronicles 21:2-4

21st Century King James Version

² And he had brethren, the sons of Jehoshaphat: Azariah, and Jehiel, and Zechariah, and Azariah, and Michael, and Shephatiah; all these were the sons of Jehoshaphat king of Israel.

³ And their father gave them great gifts of silver and gold and precious things, with fortified cities in Judah; but the kingdom he gave to Jehoram, because he was the firstborn.

⁴ Now when Jehoram had risen up to the kingdom of his father, he strengthened himself and slew all his brethren with the sword, and others also of the princes of Israel.
