2 Kings 10:23-24

23Then Jehu with Jehonadab the son of Rechab went into the house of Baal; and he said to the worshipers of Baal, “Search carefully and see that there are no servants of the Lord here with you, but only the worshipers of Baal.”

24Then they went in to offer sacrifices and burnt offerings. Now Jehu had stationed eighty men outside for himself and said, “If any of the men whom I have brought into your hands escape, the one who lets him go shall forfeit his own life for that man’s life.”
