2 Chronicles 21:3-5

American Standard Version

³ And their father gave them great gifts, of silver, and of gold, and of precious things, with fortified cities in Judah: but the kingdom gave he to Jehoram, because he was the first-born. ⁴ Now when Jehoram was risen up over the kingdom of his father, and had strengthened himself, he slew all his brethren with the sword, and divers also of the princes of Israel. ⁵ Jehoram was thirty and two years old when he began to reign; and he reigned eight years in Jerusalem.
