Threshing — Threshing is put for the corn threshed; and the corn threshed for people sorely afflicted. This is probably spoken of Babylon. The corn — Which I will cause to be threshed upon the floor. You — Unto you my people; for all the prophecies, even concerning other nations, were published to them, and for their use and comfort.
