'Kneading troughs' in the Bible

and the River hath teemed with frogs, and they have gone up and gone into thy house, and into the inner-chamber of thy bed, and on thy couch, and into the house of thy servants, and among thy people, and into thine ovens, and into thy kneading-troughs;

and the people taketh up its dough before it is fermented, their kneading-troughs are bound up in their garments on their shoulder.
