2 Kings 10:15

And he went thence and found Jonadab the son of Rechab [coming] to meet him; and he saluted him, and Ju said to him, Is thy heart right with my heart, as my heart [is] with thy heart? And Jonadab said, It is. And Ju said, If it is then, give me thy hand. And he gave him his hand, and he took him up to him into the chariot.
