Judges 20:36-39

³⁶So the children of Benjamin saw that they were smitten: for the men of Israel gave place to the Benjamites, because they trusted unto the liers in wait which they had set beside 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 there was an appointed sign between the men of Israel and the liers in wait, that they should make a great flame with smoke rise up out of the city.

³⁹And when the men of Israel retired in the battle, 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.
