2 Kings 10:15-16

15And he departed thence, and found Jehonadab the son of Rechab [coming] to meet him; and he greeted him, and said to him, Is thy heart right, as my heart is with thy heart? And Jehonadab said, It is. — If it be, give [me] thy hand. — And he gave [him] his hand; and [Jehu] took him up to him into the chariot,

16and said, Come with me, and see my zeal for Jehovah. So they made him ride in his chariot.
