2 Kings 10:23-25
New International Version
23 Then Jehu and Jehonadab son of Rekab went into the temple of Baal. Jehu said to the servants of Baal, “Look around and see that no one who serves the Lord is here with you—only servants of Baal.” 24 So they went in to make sacrifices and burnt offerings. Now Jehu had posted eighty men outside with this warning: “If one of you lets any of the men I am placing in your hands escape, it will be your life for his life.”(A)
25 As soon as Jehu had finished making the burnt offering, he ordered the guards and officers: “Go in and kill(B) them; let no one escape.”(C) So they cut them down with the sword. The guards and officers threw the bodies out and then entered the inner shrine of the temple of Baal.
