2 Kings 10:11-17

11Then Jehu killed all who were left of Ahab’s family in Jezreel, and all his nobles, close friends, and priests. He left no survivors.

12Jehu then left there and set out for Samaria. While he was traveling through Beth Eked of the Shepherds,

13Jehu encountered the relatives of King Ahaziah of Judah. He asked, “Who are you?” They replied, “We are Ahaziah’s relatives. We have come down to see how the king’s sons and the queen mother’s sons are doing.”

14He said, “Capture them alive!” So they captured them alive and then executed all forty-two of them in the cistern at Beth Eked. He left no survivors.

15When he left there, he met Jehonadab, son of Rekab, who had been looking for him. Jehu greeted him and asked, “Are you as committed to me as I am to you?” Jehonadab answered, “I am!” Jehu replied, “If so, give me your hand.” So he offered his hand and Jehu pulled him up into the chariot.

16Jehu said, “Come with me and see how zealous I am for the Lord’s cause.” So he took him along in his chariot.

17He went to Samaria and exterminated all the members of Ahab’s family who were still alive in Samaria, just as the Lord had announced to Elijah.
