Judges 20:40 WBT

³⁸  Now there was an appointed sign between the men of Israel and the liers in wait, that they should make a great flame with smoke to rise from the city.

³⁹  And 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.

⁴⁰  But when the flame began to rise from the city with a pillar of smoke, the Benjaminites looked behind them, and behold, the flame of the city ascended to heaven.

⁴¹  And when the men of Israel turned again, the men of Benjamin were amazed: for they saw that evil had come upon them.

⁴²  Therefore they turned [their backs] before the men of Israel to the way of the wilderness; but the battle overtook them; and them who [came] out of the cities they destroyed in the midst of them.
