2 Chronicles 21:3-5

21:3 Their father gave them many presents, including silver, gold, and other precious items, along with fortified cities in Judah. But he gave the kingdom to Jehoram because he was the firstborn.

21:4 Jehoram took control of his father’s kingdom and became powerful. Then he killed all his brothers, as well as some of the officials of Israel. 21:5 Jehoram was thirty-two years old when he became king and he reigned for eight years in Jerusalem.
