2 Kings 9:6-8

And he arose, and went into the house; and he poured the oil on his head, and said unto him, Thus saith Jehovah, the God of Israel, I have anointed thee king over the people of Jehovah, even over Israel. And thou shalt smite the house of Ahab thy master, that I may avenge the blood of my servants the prophets, and the blood of all the servants of Jehovah, at the hand of Jezebel. For the whole house of Ahab shall perish; and I will cut off from Ahab every man-child, and him that is shut up and him that is left at large in Israel.
