2 Kings 10:9-11

Amplified Bible

⁹ The next morning he went out and stood and said to all the people, “You are just and innocent; behold, I conspired against [Joram] my master and killed him, but who killed all these? ¹⁰ Know then [without any doubt] that there shall fall to the earth nothing of the word of the Lord, which the Lord spoke concerning the house of Ahab, for the Lord has done what He said ^[a]through His servant Elijah.”^{(A) 11} So Jehu killed all who remained of the house of Ahab in Jezreel, and all his great men and his familiar friends and his priests, until he left him without a survivor.
