2 Kings 10:11-17

11So Jehu killed everyone in Jezreel who remained of the house of Ahab, as well as all his great men and close friends and priests, leaving him without a single survivor.

12Then Jehu set out toward Samaria. At Beth-eked of the Shepherds, 13Jehu met some relatives of Ahaziah king of Judah and asked, “Who are you?”

“We are relatives of Ahaziah,” they answered, “and we have come down to greet the sons of the king and of the queen mother.”

14Then Jehu ordered, “Take them alive.” So his men took them alive, then slaughtered them at the well of Beth-eked—forty-two men. He spared none of them.

15When he left there, he found Jehonadab son of Rechab, who was coming to meet him. Jehu greeted him and asked, “Is your heart as true to mine as my heart is to yours?”

“It is!” Jehonadab replied.

“If it is,” said Jehu, “give me your hand.”

So he gave him his hand, and Jehu helped him into his chariot, 16saying, “Come with me and see my zeal for the LORD!” So he had him ride1 in his chariot.

17When Jehu came to Samaria, he struck down everyone belonging to Ahab who remained there, until he had destroyed them, according to the word that the LORD had spoken to Elijah.
