19 Now therefore call to me all the prophets of Baal, all of his worshippers, and all of his priests. Let none be absent; for I have a great sacrifice to Baal. Whoever is absent, he shall not live.” But Jehu did it in subtlety, intending that he might destroy the worshippers of Baal. 20 Jehu said, “Sanctify a solemn assembly for Baal!”
They proclaimed it. 21 Jehu sent through all Israel; and all the worshippers of Baal came, so that there was not a man left that didn’t come. They came into the house of Baal; and the house of Baal was filled from one end to another. 22 He said to him who was over the vestry, “Bring out robes for all the worshippers of Baal!”
He brought robes out to them. 23 Jehu went with Jehonadab the son of Rechab into the house of Baal. Then he said to the worshippers of Baal, “Search, and look that there are here with you none of the servants of Yahweh, but the worshippers of Baal only.” 24 They went in to offer sacrifices and burnt offerings. Now Jehu had appointed him eighty men outside, and said, “If any of the men whom I bring into your hands escape, he who lets him go, his life shall be for the life of him.” 25 It happened, as soon as he had made an end of offering the burnt offering, that Jehu said to the guard and to the captains, “Go in, and kill them! Let none escape.” They struck them with the edge of the sword; and the guard and the captains cast them out, and went to the city of the house of Baal.

(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.
