2 Kings 10:11-17

11So Jehu killed all who remained of the house of Ahab in Jezreel — all his great men, close friends, and priests — leaving him no survivors.

12Then he set out and went to Samaria. On the way, while he was at Beth-eked of the Shepherds,

13Jehu met the relatives of King Ahaziah of Judah and asked, “Who are you?” They answered, “We’re Ahaziah’s relatives. We’ve come down to greet the king’s sons and the queen mother’s sons.”

14Then Jehu ordered, “Take them alive.” So they took them alive and then slaughtered them at the pit of Beth-eked — forty-two men. He didn’t spare any of them.

15When he left there, he found Jehonadab son of Rechab coming to meet him. He greeted him and then asked, “Is your heart one with mine?” “It is,” Jehonadab replied. Jehu said, “If it is, give me your hand.” So he gave him his hand, and Jehu pulled him up into the chariot with him.

16Then he said, “Come with me and see my zeal for the Lord!” So he let him ride with him in his chariot.

17When Jehu came to Samaria, he struck down all who remained from the house of Ahab in Samaria until he had annihilated his house, according to the word of the Lord spoken to Elijah.
