Judges 20:34

Ten thousand chosen men These seem to have been a detachment from the main body, which was at Baal-tamar, and marched to attack Gibeah on one side, while the liers in wait assaulted it on the other, and while the great body of the army laboured to intercept the Benjamites, who, having pursued the Israelites that pretended to flee, now endeavoured to retreat to Gibeah. The battle was sore; but they knew not, &c. The Benjamites fought stoutly; but were not sensible of the danger they were in to be destroyed.
