2 Kings 10:23-24

23Then Jehu and Jehonadab son of Rekab went to the temple of Baal. Jehu said to the servants of Baal, “Make sure there are no servants of the Lord here with you; there must be only servants of Baal.”

24They went inside to offer sacrifices and burnt offerings. Now Jehu had stationed eighty men outside. He had told them, “If any of the men inside get away, you will pay with your lives!”
