2 Chronicles 21:5

³And their father gave them many gifts, silver, and gold, and arms, together with fortified cities in Judah: but he gave the kingdom to Jehoram, for he was the firstborn.

⁴And Jehoram entered upon his kingdom, and strengthened himself, and slew all his brothers with the sword, and some of the princes of Israel.

— 2 Chronicles 21:5 —

⁶And he walked in the way of the kings of Israel, as did the house of Ahab; for a daughter of Ahab was his wife: and he did that which was evil in the sight of the Lord:

⁷nevertheless the Lord would not utterly destroy the house of David, because of the covenant which he made with David, and as he said to him that he would give a light to him and his sons forever.
