2 Kings 10:23-24

23Then Jehu and Jehonadab son of Rekab went into the temple of Baal. Jehu said to the servants of Baal, “Look around and see that no one who serves the Lord is here with you—only servants of Baal.”

24So they went in to make sacrifices and burnt offerings. Now Jehu had posted eighty men outside with this warning: “If one of you lets any of the men I am placing in your hands escape, it will be your life for his life.”
