2 Kings 9:6-8

So Jehu got up, and they went into the house. And he poured the oil on Jehu’s head and said to him, “Thus says the LORD, the God of Israel: ‘I have anointed you king over the people of the LORD, over Israel. You shall strike the house of Ahab your master, so that I may avenge the blood of My servants the prophets, and the blood of all the servants of the LORD, [who have died] at the hands of Jezebel. For the entire house of Ahab shall perish, and I will cut off from Ahab every male, both bond and free, in Israel.
