Judges 3:26-28

26But Ehud had escaped while they delayed, and passed beyond the stone images and escaped to Seirah.

27And it happened, when he arrived, that he blew the trumpet in the mountains of Ephraim, and the children of Israel went down with him from the mountains; and he led them.

28Then he said to them, “Follow me, for the Lord has delivered your enemies the Moabites into your hand.” So they went down after him, seized the fords of the Jordan leading to Moab, and did not allow anyone to cross over.
