2 Kings 10:12

8 When the messenger arrived, he told Jehu, “They have brought the heads of the sons of the king.” And Jehu ordered, “Pile them in two heaps at the entrance of the gate until morning.”

9 The next morning, Jehu went out and stood before all the people and said, “You are innocent. It was I who conspired against my master and killed him. But who killed all these?

10 Know, then, that not a word the LORD has spoken against the house of Ahab will fail, for the LORD has done what He promised through His servant Elijah.”

11 So 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.

12 Then Jehu set out toward Samaria. At Beth-eked of the Shepherds,

13 Jehu 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.”

14 Then 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.

15 When 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,

16 saying, “Come with me and see my zeal for the LORD!” So he had him ride in his chariot.
