2 Kings 10:15-16

15When Jehu left there, he met Jehonadab son of Recab, who was coming to meet him. After they had greeted each other, Jehu said to him, “Are you as loyal to me as I am to you?” “Yes, I am,” Jehonadab replied. “If you are,” Jehu said, “then give me your hand.” So Jehonadab put out his hand, and Jehu helped him into the chariot.

16Then Jehu said, “Now come with me, and see how devoted I am to the Lord.” So Jehonadab rode along with him.
