15 And when he had gone away from there, he came across Jehonadab, the son of Rechab: and he said good-day to him, and said to him, Is your heart true to mine, as mine is to yours? And Jehonadab in answer said, It is; and Jehu said, If it is, give me your hand. And he gave him his hand, and he made him come up into his carriage. 16 And he said, Come with me and see how I am on fire for the Lord's cause. So he made him go with him in his carriage. 17 And when he came to Samaria, he put to death all those of Ahab's family who were still in Samaria, till there were no more of them, as the Lord had said to Elijah.
18 Then Jehu got all the people together and said to them, Ahab was Baal's servant in a small way, but Jehu will be his servant on a great scale. 19 Now send for all the prophets of Baal and all his servants and all his priests, to come to me; let no one keep away: for I have a great offering to make to Baal; anyone who is not present, will be put to death. This Jehu did with deceit, his purpose being the destruction of the servants of Baal. 20 And Jehu said, Let there be a special holy meeting for the worship of Baal. So a public statement was made. 21 And Jehu sent out through all Israel; and all the servants of Baal came, not one kept away. And they came into the house of Baal, so that it was full from end to end. 22 And Jehu said to him who kept the robes, Get out robes for all the servants of Baal. So he got out robes for them. 23 And Jehu, with Jehonadab, the son of Rechab, went into the house of Baal; and he said to the servants of Baal, Make a search with care, to see that no servant of the Lord is with you, but 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.
