2 Kings 10:11-17

11Then Jehu killed all who were left of Ahab’s relatives living in Jezreel and all his important officials, his personal friends, and his priests. So Ahab was left without a single survivor.

12Then Jehu set out for Samaria. Along the way, while he was at Beth-eked of the Shepherds,

13he met some relatives of King Ahaziah of Judah. “Who are you?” he asked them. And they replied, “We are relatives of King Ahaziah. We are going to visit the sons of King Ahab and the sons of the queen mother.”

14“Take them alive!” Jehu shouted to his men. And they captured all forty-two of them and killed them at the well of Beth-eked. None of them escaped.

15When Jehu left there, he met Jehonadab son of Recab, who was coming to meet him. After they had greeted each other, Jehu said to him, “Are you as loyal to me as I am to you?” “Yes, I am,” Jehonadab replied. “If you are,” Jehu said, “then give me your hand.” So Jehonadab put out his hand, and Jehu helped him into the chariot.

16Then Jehu said, “Now come with me, and see how devoted I am to the Lord.” So Jehonadab rode along with him.

17When Jehu arrived in Samaria, he killed everyone who was left there from Ahab’s family, just as the Lord had promised through Elijah.
