15 And when he was departed thence, he lighted on Jehonadab the son of Rechab coming to meet him; and he saluted him, and said to him, Is thy heart right, as my heart is with thy heart? And Jehonadab answered, It is. If it be, give me thy hand. And he gave him his hand; and he took him up to him into the chariot. 16 And he said, Come with me, and see my zeal for Jehovah. So they made him ride in his chariot. 17 And when he came to Samaria, he smote all that remained unto Ahab in Samaria, till he had destroyed him, according to the word of Jehovah, which he spake to Elijah.
18 And Jehu gathered all the people together, and said unto them, Ahab served Baal a little; but Jehu will serve him much. 19 Now therefore call unto me all the prophets of Baal, all his worshippers, and all his priests; let none be wanting: for I have a great sacrifice [to do] to Baal; whosoever shall be wanting, he shall not live. But Jehu did it in subtlety, to the intent that he might destroy the worshippers of Baal. 20 And Jehu said, Sanctify a solemn assembly for Baal. And they proclaimed it. 21 And Jehu sent through all Israel: and all the worshippers of Baal came, so that there was not a man left that came not. And they came into the house of Baal; and the house of Baal was filled from one end to another. 22 And he said unto him that was over the vestry, Bring forth vestments for all the worshippers of Baal. And he brought them forth vestments. 23 And Jehu went, and Jehonadab the son of Rechab, into the house of Baal; and he said unto the worshippers of Baal, Search, and look that there be here with you none of the servants of Jehovah, but the worshippers of Baal only.

(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.
