Judges 3:26-28

26Now Ehud escaped while they lingered, and he passed beyond the sculptured stones and escaped to Seirah.

27When he had arrived, he blew a 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.

28And he said to them, “Pursue them, for the Lord has handed over your enemies the Moabites to you.” So they went down after him and seized the fords of the Jordan opposite Moab and did not allow anyone to cross.
