Judges 20:36-39

³⁶So the children of Benjamin saw that they were smitten. And 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 hastened, and rushed upon Gibeah; and the liers-in-wait drew forth, 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 beacon 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.'
