7 You shall strike the house of Ahab your master, that I may avenge the blood of my servants the prophets, and the blood of all the servants of Yahweh, at the hand of Jezebel. 8 For the whole house of Ahab shall perish. I will cut off from Ahab everyone who urinates against a wall, [1] both him who is shut up and him who is left at large in Israel. 9 I will make the house of Ahab like the house of Jeroboam the son of Nebat, and like the house of Baasha the son of Ahijah. 10 The dogs will eat Jezebel on the plot of ground of Jezreel, and there shall be none to bury her.” He opened the door, and fled.

11 Then Jehu came forth to the servants of his lord: and one said to him, “Is all well? Why did this mad fellow come to you?”

He said to them, “You know the man and what his talk was.” 12 They said, “That is a lie. Tell us now.”

He said, “He said to me, ‘Thus says Yahweh, I have anointed you king over Israel.’” 13 Then they hurried, and took every man his garment, and put it under him on the top of the stairs, and blew the trumpet, saying, “Jehu is king.”

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.

Commentary on 2 Kings 9:11-15

(Read 2 Kings 9:11-15)

Those who faithfully deliver the Lord's message to sinners, have in all ages been treated as madmen. Their judgment, speech, and conduct are contrary to those of other men; they endure much in pursuit of objects, and are influenced by motives, into which the others cannot enter. But above all, the charge is brought by the worldly and ungodly of all sorts, who are mad indeed; while the principles and practice of the devoted servants of God, prove to be wise and reasonable. Some faith in the word of God, seems to have animated Jehu to this undertaking.
