2 Chronicles 21:4-7

4Now when Jehoram had risen over his father’s kingdom and made himself strong, he slew all his brothers with the sword, along with some of the officers of Israel.

5Jehoram was 32 years old when he became king and he reigned in Jerusalem eight years.

6He walked in the way of the kings of Israel, just as the house of Ahab did (for Ahab’s daughter was his wife), and he did evil in the eyes of Adonai.

7However, Adonai was not willing to destroy the house of David because of the covenant He had made with David, and since He had spoken a word to give a lamp to him and his sons always.
