Judges 20:38-40 ▼

38 Now the appointed sign between the men of Israel and the men in ambush was that they would make a great cloud of smoke rise from the city.

39 So the men of Israel had turned around in the battle, and Benjamin had begun to strike and slay about thirty men of Israel, for they said, “Surely they are defeated before us, as in the first battle.”

40 But the cloud began to rise from the city in a column of smoke, and Benjamin turned behind them; and behold, the whole city was going up in smoke to heaven.
