2 Kings 10:15,16

He lighted on Jehonadab A Kenite, (1 Chronicles 2:55,) and a man of singular prudence and piety, as appears from this history, and from Jeremiah 35:6; from him descended the race of the Rechabites. And he saluted him That is, Jehu saluted Jehonadab. It is likely Jehonadab was in great favour with the people, on account of the strictness of his life and virtue, and that this, in part, induced Jehu to speak so kindly to him, and court his friendship. And said, Is thy heart right, &c. Dost thou love me as sincerely and fervently as I love thee, and approve of my present proceedings, as I approve of thy institutions? If it be, give me thy hand As a sign of friendship and fidelity. These seem to be the words of Jehu. And he said, Come, and see my zeal for the Lord For the vindication of his honour, and the execution of his commands. Do not believe my words, but mine actions, which thine eyes shall behold. So they made him ride in his chariot The servants opened the door of his chariot, and Jehu took him up into it. And while he thus put some honour upon Jehonadab, he received more honour from him. For all pious and sober people would think the better of Jehu when they saw Jehonadab in the chariot with him. “This is not the only time,” says Henry, “that the piety of some has been made to serve the policy of others; and that designing men have strengthened themselves by drawing good men into their interests.”
