2 Kings 10:24-25

24Then they went in to offer sacrifices and burnt offerings.

Now Jehu had stationed for himself eighty men outside, and he had said, “1The one who permits any of the men whom I bring into your hands to escape 2shall give up his life in exchange.”

25Then it came about, as soon as he had finished offering the burnt offering, that Jehu said to the 34guard and to the royal officers, “5Go in, 6kill them; let none come out.” And they 7killed them with the edge of the sword; and the 8guard and the royal officers threw them out, and went to the 9inner room of the house of Baal.
