Judges 20:37 DBY

³⁵  And the LORD defeated Benjamin before Israel; and the men of Israel destroyed twenty-five thousand one hundred men of Benjamin that day; all these were men who drew the sword.

³⁶  So the Benjaminites saw that they were defeated. The men of Israel gave ground to Benjamin, because they trusted to the men in ambush whom they had set against Gib'e-ah.

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.'
