Jehonadab in the Bible

Next he went from there and found Jehonadab the son of Recab to meet him. He greeted him and asked him, "{Is your heart right with me as my heart is with you}?" Then Jehonadab said, "Yes, it is. Give your hand!" And he gave his hand and took him up to him on the chariot.

"If it is," Jehu replied, "Put out your hand." So Jehonadab stuck out his hand, and Jehu took him up to stand in his chariot. He told him, "Come with me and see my enthusiasm for the LORD!" So Jehu had Jehonadab ride in his chariot.

Then Jehu and Jehonadab the son of Recab came [to] the temple of Baal, and he said to the servants of Baal, "Search and see that there is none of the servants of Yahweh here with you; only those who serve Baal."
