6 So he arose, and went into the house; and the young man poured the oil on his head, saying to him, "Thus says the Lord the God of Israel, I anoint you king over the people of the Lord, over Israel. 7 And you shall strike down the house of Ahab your master, that I may avenge on Jez'ebel the blood of my servants the prophets, and the blood of all the servants of the Lord. 8 For the whole house of Ahab shall perish; and I will cut off from Ahab every male, bond or free, in Israel. 9 And I will make the house of Ahab like the house of Jerobo'am the son of Nebat, and like the house of Ba'asha the son of Ahi'jah. 10 And the dogs shall eat Jez'ebel in the territory of Jezreel, and none shall bury her." Then he opened the door, and fled.

(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.
