7 You are to destroy the family of Ahab, your master. In this way, I will avenge the murder of my prophets and all the Lord 's servants who were killed by Jezebel. 8 The entire family of Ahab must be wiped out. I will destroy every one of his male descendants, slave and free alike, anywhere in Israel. 9 I will destroy the family of Ahab as I destroyed the families of Jeroboam son of Nebat and of Baasha son of Ahijah. 10 Dogs will eat Ahab's wife Jezebel at the plot of land in Jezreel, and no one will bury her." Then the young prophet opened the door and ran.

Commentary on 2 Kings 9:1-10
(Read 2 Kings 9:1-10)
In these and the like events, we must acknowledge the secret working of God, disposing men to fulfil his purposes respecting them. Jehu was anointed king over Israel, by the Lord's special choice. The Lord still had a remnant of his people, and would yet preserve his worship among them. Of this Jehu was reminded. He was commanded to destroy the house of Ahab, and, as far as he acted in obedience to God, and upon right principles, he needed not to regard reproach or opposition. The murder of God's prophets is strongly noticed. Jezebel persisted in idolatry and enmity to Jehovah and his servants, and her iniquity was now full.
