Judges 3:26-28

26Ehud, however, had escaped while the servants waited. He passed by the idols and escaped to Seirah.

27On arriving in Seirah, he blew the ram’s horn throughout the hill country of Ephraim. The Israelites came down with him from the hills, and he became their leader. 28“Follow me,” he told them, “for the LORD has delivered your enemies the Moabites into your hand.”

So they followed him down and seized the fords of the Jordan leading to Moab, and they did not allow anyone to cross over.
