Judges 20:29-35

So Israel set men in ambush around Gibeah. The [fighting men of the] sons of Israel went up against the sons of Benjamin on the third day and placed themselves in battle formation against Gibeah as at other times. The Benjamites went out against their army and were lured away from the city, and they began to strike and kill some of the people as at other times, on the highways, one of which goes up to Bethel and the other to Gibeah, and in the open country, about thirty men of Israel. And the Benjamites said, “They are defeated before us, as at the first.” But the sons of Israel said, “Let us flee and lure them away from the city to the highways.” Then all the men of Israel got up from their places and placed themselves in battle formation at Baal-tamar; and the men of Israel [who were] in ambush rushed from their place in the plain of Maareh-geba. When the ten thousand choice [fighting] men from all Israel came against Gibeah, the battle was hard and fierce; but the Benjamites did not realize that disaster was about to strike them. And the LORD struck down [the tribe of] Benjamin before Israel, so that the sons of Israel destroyed twenty-five thousand one hundred men of Benjamin that day, all of whom were swordsmen.
