Judges 20:34-36

Common English Bible

³⁴ Ten thousand specially chosen men from all the Israelites came against Gibeah. The fighting was fierce, and the Benjaminites didn’t realize that disaster was almost on them. ³⁵ The Lord wiped out the Benjaminites before Israel. The Israelites slaughtered twenty-five thousand one hundred Benjaminite men that day, all of them armed with swords. ³⁶ Then the Benjaminites saw that they had been defeated.

The Israelites had given ground to the Benjaminites because they relied on the ambush that they had set around Gibeah.
