'Floor' in the Bible

Have no joy, O Israel, and do not be glad like the nations; for you have been untrue to your God; your desire has been for the loose woman's reward on every grain-floor.

The floor and the winepress shall not feed them, and the new wine shall fail in her.

Therefore they shall be as the morning cloud, and as the early dew that passeth away, as the chaff that is driven with the whirlwind out of the floor, and as the smoke out of the chimney.
