God finally defeated the Benjamites - 25,100 killed

Judges 20:27-25 And the Israelites inquired of the LORD. (In those days the ark of the covenant of God was there, with Phinehas son of Eleazar, the son of Aaron, ministering before it.) They asked, "Shall we go up again to battle with Benjamin our brother, or not?"
The LORD responded, "Go, for tomorrow I will give them into your hands."

Then Israel set an ambush around Gibeah. They went up against the Benjamites on the third day and took up positions against Gibeah as they had done before. The Benjamites came out to meet them and were drawn away from the city. They began to inflict casualties on the Israelites as before, so that about thirty men fell in the open field and on the roads—the one leading to Bethel and the other to Gibeah.

While the Benjamites were saying, "We are defeating them as before," the Israelites were saying, "Let's retreat and draw them away from the city to the roads."

All the men of Israel moved from their places and took up positions at Baal Tamar, and the Israelite ambush charged out of its place on the west of Gibeah. Then ten thousand of Israel's finest men made a frontal attack on Gibeah. The fighting was so heavy that the Benjamites did not realize how near disaster was. The LORD defeated Benjamin before Israel, and on that day the Israelites struck down 25,100 Benjamites, all armed with swords.

PERSONAL COMMENTARY

After allowing 40,000 Israelites to be killed by the Benjamites even though God directed the Israelites to fight, God finally defeats the Benjamites.
