2 Chronicles 21:3-7

Their father had given each of them valuable gifts of silver, gold, and costly items, and also some of Judah’s fortified towns. However, he designated Jehoram as the next king because he was the oldest. But when Jehoram had become solidly established as king, he killed all his brothers and some of the other leaders of Judah. Jehoram was thirty-two years old when he became king, and he reigned in Jerusalem eight years. But Jehoram followed the example of the kings of Israel and was as wicked as King Ahab, for he had married one of Ahab’s daughters. So Jehoram did what was evil in the LORD’s sight. But the LORD did not want to destroy David’s dynasty, for he had made a covenant with David and promised that his descendants would continue to rule, shining like a lamp forever.
