2 Kings 10:24-25

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!”

25When he finished offering the burnt sacrifice, Jehu ordered the royal guard and officers, “Come in and strike them down! Don’t let any escape!” So the royal guard and officers struck them down with the sword and left their bodies lying there. Then they entered the inner sanctuary of the temple of Baal.
