Parallel
Judges 20:36
King James Version (1769 Blayney revision, with Apocrypha) · Berean Standard Bible
So the children of Benjamin saw that they were smitten: for the men of Israel gave place to the Benjamites, because they trusted unto the liers in wait which they had set beside Gibeah.
Then the Benjamites realized they had been defeated. Now the men of Israel had retreated before Benjamin because they were relying on the ambush they had set against Gibeah.
