Judges 20:34-37 New International Version (NIV)

34. Then ten thousand of Israel’s able young men made a frontal attack on Gibeah. The fighting was so heavy that the Benjamites did not realize how near disaster was.

35. The Lord defeated Benjamin before Israel, and on that day the Israelites struck down 25,100 Benjamites, all armed with swords.

36. Then the Benjamites saw that they were beaten. Now the men of Israel had given way before Benjamin, because they relied on the ambush they had set near Gibeah.

37. Those who had been in ambush made a sudden dash into Gibeah, spread out and put the whole city to the sword.
