Judges 20:36-39

³⁶So the children of Benjamin saw that they were smitten; for the men of Israel gave place to Benjamin, because they trusted unto the liers-in-wait whom they had set against Gibeah.

³⁷And the liers-in-wait hasted, and rushed upon Gibeah; and the liers-in-wait drew themselves along, and smote all the city with the edge of the sword.

³⁸Now the appointed sign between the men of Israel and the liers-in-wait was, that they should make a great cloud of smoke rise up out of the city.

³⁹And the men of Israel turned in the battle, and Benjamin began to smite and kill of the men of Israel about thirty persons; for they said, Surely they are smitten down before us, as in the first battle.
