2 Kings 10:24-25

24So they went in to offer sacrifices and burnt offerings. But Jehu had stationed 80 of his men outside. He said ⌞to them⌟, “If any of the people I’m putting in your hands escape, you will pay for their lives with yours.”

25When the burnt offerings had been made, Jehu said to the guards and attendants, “Kill them. Don’t let anyone get away.” So they used swords to kill the Baal worshipers and threw out the bodies until the guards and attendants came to the stronghold in the temple of Baal.
