When he had finished making the burnt offering, Jehu said to the guards and officers, “Go in and kill them. Do not let anyone out.” So the guards and officers put them to the sword, threw the bodies out, and went into the inner room of the temple of Baal.
Jewish Publication Society of America Version (JPS1917) - 2 Kings 10:25 >And 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.
