2 Kings 10:24-25

24And they went in to offer sacrifices and burnt-offerings. Now Jehu had appointed him fourscore men without, and said, If any of the men whom I bring into your hands escape, he that letteth him go, his life shall be for the life of him.

25And it came to pass, as soon as he had made an end of offering the burnt-offering, that Jehu said to the guard and to the captains, Go in, and slay them; let none come forth. And they smote them with the edge of the sword; and the guard and the captains cast them out, and went to the city of the house of Baal.
