So the children of Benjamin saw that they were struck, for the men of Israel yielded to Benjamin because they trusted the ambushers whom they had set against 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.
