2 Kings 10:23-24

23Then Jehu and Jehonadab son of Rechab went into the temple of Baal, and he said to the worshippers of Baal, “Search and look that there is here with you none of the servants of Adonai—only servants of Baal.”

24Then they went in to offer sacrifices and burnt offerings. Now Jehu had already stationed 80 of his men outside and said, “If any of the men whom I am bringing into your hands escapes, your life will be for his life.”
