Judges 20:34-36

Complete Jewish Bible

³⁴ Ten thousand men chosen out of all Isra’el came over to attack Giv‘ah, and the combat was intense. But the army of Binyamin didn’t know that they were about to be defeated. ³⁵ For Adonai routed Binyamin in Isra’el’s presence; that day the army of Isra’el destroyed 25,100 men of Binyamin, all of whom carried swords; ³⁶ and the people of Binyamin realized that they had been beaten.

The men of Isra’el, trusting the ones they had put in place to ambush Binyamin, gave ground to the men of Binyamin.
