2 Kings 10:15 NASB95

[15] Now when he had departed from there, he met Jehonadab the son of Rechab coming to meet him; and he greeted him and said to him, "Is your heart right, as my heart is with your heart?" And Jehonadab answered, "It is." Jehu said, "If it is, give me your hand." And he gave him his hand, and he took him up to him into the chariot.
