15 And he goeth thence, and findeth Jehonadab son of Rechab—to meet him, and blesseth him, and saith unto him, 'Is thy heart right, as my heart 'is' with thy heart?' and Jehonadab saith, 'It is;'—'Then it is; give thy hand;' and he giveth his hand, and he causeth him to come up into him into the chariot, 16 and saith, 'Come with me, and look on my zeal for Jehovah;' and they cause him to ride in his chariot. 17 And he cometh in to Samaria, and smiteth all those left to Ahab in Samaria, till his destroying him, according to the word of Jehovah that He spake unto Elisha.
18 And Jehu gathereth the whole of the people, and saith unto them, 'Ahab served Baal a little—Jehu doth serve him much: 19 and now, all the prophets of Baal, all his servants, and all his priests, call ye unto me; let not a man be lacking, for a great sacrifice I have for Baal; every one who is lacking—he doth not live;' and Jehu hath done 'it' in subtilty, in order to destroy the servants of Baal. 20 And Jehu saith, 'Sanctify a restraint for Baal;' and they proclaim 'it'. 21 And Jehu sendeth into all Israel, and all the servants of Baal come in, and there hath not been left a man who hath not come in; and they come in to the house of Baal, and the house of Baal is full—mouth to mouth. 22 And he saith to him who 'is' over the wardrobe, 'Bring out clothing to all servants of Baal;' and he bringeth out to them the clothing. 23 And Jehu goeth in, and Jehonadab son of Rechab, to the house of Baal, and saith to the servants of Baal, 'Search and see, lest there be here with you of the servants of Jehovah—but, the servants of Baal by themselves.'

(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.
