2 Kings 10:14

10Know now that nothing will fall to the earth of the LORD’s word, which the LORD spoke concerning Ahab’s house. For the LORD has done that which he spoke by his servant Elijah.”

11So Jehu struck all that remained of Ahab’s house in Jezreel, with all his great men, his familiar friends, and his priests, until he left him no one remaining.

12He arose and departed, and went to Samaria. As he was at the shearing house of the shepherds on the way,

13Jehu met with the brothers of Ahaziah king of Judah, and said, “Who are you?” They answered, “We are the brothers of Ahaziah. We are going down to greet the children of the king and the children of the queen.”

14He said, “Take them alive!” They took them alive, and killed them at the pit of the shearing house, even forty-two men. He didn’t leave any of them.

15When he had departed from there, he met Jehonadab the son of Rechab coming to meet him. He greeted him, and said to him, “Is your heart right, as my heart is with your heart?” Jehonadab answered, “It is.” “If it is, give me your hand.” He gave him his hand; and he took him up to him into the chariot.

16He said, “Come with me, and see my zeal for the LORD.” So they made him ride in his chariot.

17When he came to Samaria, he struck all who remained to Ahab in Samaria, until he had destroyed them, according to the LORD’s word which he spoke to Elijah.

18Jehu gathered all the people together, and said to them, “Ahab served Baal a little, but Jehu will serve him much.
