2KI 10:15

15 When Jehu had left there, he met Jehonadab son of Recab coming to meet him. Jehu greeted him and said to him, “Is your heart with me, as my heart is with yours?” Jehonadab answered, “It is.” Jehu said, “If it is, give me your hand.” So he gave Jehu his hand, and Jehu took Jehonadab up with him into the chariot.
