2 Chronicles 21:3-5

New King James Version

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

⁴ Now when Jehoram ^[a]was established over the kingdom of his father, he strengthened himself and killed all his brothers with the sword, and also others of the princes of Israel.

^5 (A)Jehoram was thirty-two years old when he became king, and he reigned eight years in Jerusalem.
