Judges 20:36-38

Amplified Bible

³⁶ So the Benjamites realized that they were defeated. Then men of Israel gave ground to the Benjamites, because they relied on the men in ambush whom they had placed against Gibeah. ³⁷ Then the men in ambush quickly rushed and attacked Gibeah; and the men in ambush also deployed and struck the entire city with the edge of the sword. ³⁸ Now the appointed signal between the men of Israel and the men in ambush was that they would make a great cloud of smoke rise from the city.
