2 Kings 10:10-17

You can be sure that the message of the LORD that was spoken concerning Ahab’s family will not fail. The LORD declared through his servant Elijah that this would happen.” Then 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. Then Jehu set out for Samaria. Along the way, while he was at Beth-eked of the Shepherds, he 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.” “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. When 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. Then Jehu said, “Now come with me, and see how devoted I am to the LORD.” So Jehonadab rode along with him. When Jehu arrived in Samaria, he killed everyone who was left there from Ahab’s family, just as the LORD had promised through Elijah.
