Charles Ellicott Commentary Judges 3:28

"And he said unto them, Follow after me; for Jehovah hath delivered your enemies the Moabites into your hand. And they went down after him, and took the fords of the Jordan against the Moabites, and suffered not a man to pass over." — Judges 3:28 (ASV)

The Lord hath delivered your enemies the Moabites into your hand. —Compare to Judges 7:9-15; 1 Samuel 17:47; 1 Kings 22:12.

Took the fords of Jordan. —This was a matter of extreme importance. The fords of Jordan were few, and far distant from each other (Joshua 2:7). The steep ravine through which it flows forms a natural barrier to Western Palestine, and by securing the fords, they cut off from the Moabites all chance of aid. The vehement rapidity of Ehud’s movements had rendered their escape impossible.

Suffered not a man to pass over. —Compare to Judges 12:5-6. It was a massacre of vengeance, like the Sicilian Vespers, or the massacre of the English of the Pale in Ireland, or that of the Danes in England on St. Brice’s day.
