Judges 3:26-28

26But Ehud escaped while they were lingering, passed beyond the idols and escaped to Seirah.

27When he arrived, he blew the shofar in the hill country of Ephraim, so Bnei-Yisrael went down with him from the hill country, and he was in front of them.

28He said to them, “Follow me, for Adonai has delivered your enemies the Moabites into your hand.” So they went down after him and seized the fords of the Jordan opposite Moab, and allowed no one to cross over.
