The historian, having related the preliminary incidents, now comes to the final issue which forms the subject matter of his narrative. On a certain occasion, as on many previous ones, the Ammonites were encamped in Gilead, with the intention of dispossessing the Israelites of the whole country, or at least as far as the river Jabbok Judges 11:13, and of invading the West-Jordanic tribes. The children of Israel on the East of Jordan assembled together to resist them, and pitched their camp in Mizpeh. The narrative proceeds to detail what happened.
Mizpeh - , as its name, "watch-tower" or "look-out" indicates was situated on a height of Mount Gilead, and was, as such, a strong post. It is almost always written, "THE Mizpeh," or watch-tower. Four or five places of the name occur in Scripture.

The children of Ammon were gathered together - Literally, they cried against Israel - they sent out criers in different directions to stir up all the enemies of Israel; and when they had made a mighty collection, they encamped in Gilead.

Then the children of Ammon were gathered together,.... By a crier, as Jarchi; they had passed over Jordan, as in Judges 10:9 and had been distressing three of the tribes of Israel on that side; but now being informed, by an herald at arms, that the children of Israel, on the other side Jordan, were risen up in defence of their country, rights, and liberties, the children of Ammon came back and crossed over Jordan again:
and encamped in Gilead; in the land of Gilead, part of which belonged to the tribes of Reuben and Gad, and the other part to the half tribe of Manasseh:
and the children of Israel assembled themselves together, and encamped at Mizpeh: of which name there were several cities in the land of Israel, on both sides Jordan; this must design a place on the other side Jordan, either in the tribe of Gad or Manasseh, for it seems there was of this name in each, see Genesis 31:49.

the children of Ammon were gathered together--From carrying on guerrilla warfare, the Ammonites proceeded to a continued campaign. Their settled aim was to wrest the whole of the trans-jordanic territory from its actual occupiers. In this great crisis, a general meeting of the Israelitish tribes was held at Mizpeh. This Mizpeh was in eastern Manasseh (Joshua 11:3).

Mizpeh - That Mizpeh which was beyond Jordan.
