Judges 3:27-30

It came about when he had arrived, that he blew the trumpet in the hill country of Ephraim; and the sons of Israel went down with him from the hill country, and he was in front of them. He said to them, “Pursue them, for the LORD has given your enemies the Moabites into your hands.” So they went down after him and seized the fords of the Jordan opposite Moab, and did not allow anyone to cross. They struck down at that time about ten thousand Moabites, all robust and valiant men; and no one escaped. So Moab was subdued that day under the hand of Israel. And the land was undisturbed for eighty years.
