Judges 20:29-35

29So Israel hid men in ambush outside Gibeah.

30The Israelites attacked the Benjaminites the next day; they took their positions against Gibeah just as they had done before.

31The Benjaminites attacked the army, leaving the city unguarded. They began to strike down their enemy just as they had done before. On the main roads (one leads to Bethel, the other to Gibeah) and in the field, they struck down about thirty Israelites.

32Then the Benjaminites said, “They are defeated just as before.” But the Israelites said, “Let’s retreat and lure them away from the city into the main roads.”

33All the men of Israel got up from their places and took their positions at Baal Tamar, while the Israelites hiding in ambush jumped out of their places west of Gibeah.

34Ten thousand men, well-trained soldiers from all Israel, then made a frontal assault against Gibeah – the battle was fierce. But the Benjaminites did not realize that disaster was at their doorstep.

35The Lord annihilated Benjamin before Israel; the Israelites struck down that day 25,100 sword-wielding Benjaminites.
