15 After he left there, he came upon Jehonadab son of Rekab, who was on his way to meet him. Jehu greeted him and said, "Are you in accord with me, as I am with you?" "I am," Jehonadab answered. "If so," said Jehu, "give me your hand." So he did, and Jehu helped him up into the chariot. 16 Jehu said, "Come with me and see my zeal for the Lord." Then he had him ride along in his chariot. 17 When Jehu came to Samaria, he killed all who were left there of Ahab's family; he destroyed them, according to the word of the Lord spoken to Elijah.

Jehu Wipes Out the Worship of Baal

18 Then Jehu brought all the people together and said to them, "Ahab served Baal a little; Jehu will serve him much. 19 Now summon all the prophets of Baal, all his servants and all his priests. See that no one is missing, because I am going to hold a great sacrifice for Baal. Anyone who fails to come will no longer live." But Jehu was acting deceptively in order to destroy the servants of Baal. 20 Jehu said, "Call an assembly in honor of Baal." So they proclaimed it. 21 Then he sent word throughout Israel, and all the servants of Baal came; not one stayed away. They crowded into the temple of Baal until it was full from one end to the other. 22 And Jehu said to the keeper of the wardrobe, "Bring robes for all the servants of Baal." So he brought out robes for them. 23 Then Jehu and Jehonadab son of Rekab went into the temple of Baal. Jehu said to the servants of Baal, "Look around and see that no one who serves the Lord is here with you-only servants of Baal."

Commentary on 2 Kings 10:15-28

(Read 2 Kings 10:15-28)

Is thine heart right? This is a question we should often put to ourselves. I make a fair profession, have gained a reputation among men, but, is my heart right? Am I sincere with God? Jehonadab owned Jehu in the work, both of revenge and of reformation. An upright heart approves itself to God, and seeks no more than his acceptance; but if we aim at the applause of men, we are upon a false foundation. Whether Jehu looked any further we cannot judge. The law of God was express, that idolaters were to be put to death. Thus idolatry was abolished for the present out of Israel. May we desire that it be rooted out of our hearts.
