Then Gideon said, Because of this, when the Lord has given Zebah and Zalmunna into my hands, I will have you stretched on a bed of thorns of the waste land and on sharp stems, and have you crushed as grain is crushed on a grain-floor.

Then he took the responsible men of the town and had them crushed on a bed of thorns and sharp stems.
