2 Kings 10:24-25

24So they went into the temple to offer sacrifices and burnt offerings. But Jehu had put 80 of his men outside the temple. He had said to them, ‘Do not let any of these men escape. If you let anyone escape, I will punish you with death.’

25When Jehu had finished offering the sacrifices, he said to the guards and the soldiers, ‘Go into the temple and kill all Baal's servants. Do not let any of them escape.’ So the guards and soldiers used their swords to cut all the people down. They threw the dead bodies out of the temple. Then they went into the inside room of the temple.
