Judges 20:37-39

Revised Standard Version

³⁷ And the men in ambush made haste and rushed upon Gib′e-ah; the men in ambush moved out and smote all the city with the edge of the sword. 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.”
