Judges 20:38-40

Darby Translation

³⁸ Now there was an appointed sign between the men of Israel and the ambush, that they should make a thick column of smoke rise up out of the city.

³⁹ And when the men of Israel turned back in the battle, Benjamin began to smite, slaying of the men of Israel about thirty men; for they said, Surely they are quite routed before us as in the first battle.

⁴⁰ And when the burning began to rise up out of the city as a pillar of smoke, Benjamin looked behind, and behold, the whole city ascended [in smoke] to the heavens.
