Judges 3:26-30

And Ehud escaped while they tarried, and passed beyond the quarries, and escaped unto Seirath.

And it came to pass, when he was come, that he blew a trumpet in the mountain of Ephraim, and the children of Israel went down with him from the mount, and he before them.

And he said unto them, Follow after me: for the LORD hath delivered your enemies the Moabites into your hand. And they went down after him, and took the fords of Jordan toward Moab, and suffered not a man to pass over.

And they slew of Moab at that time about ten thousand men, all lusty, and all men of valour; and there escaped not a man.

So Moab was subdued that day under the hand of Israel. And the land had rest fourscore years.
