10:15 And when he was departed thence, he lighted on Jehonadab the son of Rechab [coming] to meet him: and he {g} saluted him, and said to him, Is thine heart right, as my heart [is] with thy heart? And Jehonadab answered, It is. If it be, give [me] thine hand. And he gave [him] his hand; and he took him up to him into the chariot.
(g) For he feared God, and lamented the wickedness of those times: therefore Jehu was glad to join with him: of Rechab read Jer 35:2.
10:15 Rechab - A Kenite, 1Chron 2:55, and a man of singular prudence and piety. Coming - To congratulate with him, for the destruction of that wicked family; and to encourage him to proceed in fulfilling the will of God. Him - Jehu saluted Jehonadab. Is, and c. - Dost thou heartily approve of me, and my present proceedings.
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.
