Judges 20:38-40

Revised Standard Version

³⁸ Now the appointed signal between the men of Israel and the men in ambush was that when they made a great cloud of smoke rise up out of the city ³⁹ the men of Israel should turn in battle. Now Benjamin had begun to smite and kill about thirty men of Israel; they said, “Surely they are smitten down before us, as in the first battle.” ⁴⁰ But when the signal began to rise out of the city in a column of smoke, the Benjaminites looked behind them; and behold, the whole of the city went up in smoke to heaven.
