2 Chronicles 21:3-5

Darby Translation

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

⁴ And Jehoram established himself over the kingdom of his father, and strengthened himself; and he slew all his brethren with the sword, and [certain] also of the princes of Israel.

⁵ Jehoram was thirty-two years old when he began to reign; and he reigned eight years in Jerusalem.
