Babylon had been a threshing instrument by which, and a threshing-floor in which, God had threshed many other nations; God now intended to make it as a threshing-floor wherein he would thresh the Chaldeans. It is time to thresh her: some think because of the next words, that the words were better translated it is time to tread her, (so the word properly signifies,) as men use to prepare their threshing-floors against the time of harvest, for the time of this harvest was near; her harvest signifieth the harvest which the justice of God would have from the ruin of the Chaldeans.
