2 Kings 10:24-25

24So they were all inside the temple to offer sacrifices and burnt offerings. Now Jehu had stationed eighty of his men outside the building and had warned them, “If you let anyone escape, you will pay for it with your own life.”

25As soon as Jehu had finished sacrificing the burnt offering, he commanded his guards and officers, “Go in and kill all of them. Don’t let a single one escape!” So they killed them all with their swords, and the guards and officers dragged their bodies outside. Then Jehu’s men went into the innermost fortress of the temple of Baal.
