'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 grain-floor and the place where the grapes are crushed will not give them food; there will be no new wine for them.

So they will be like the morning cloud, like the dew which goes early away, like the dust of the grain which the wind is driving out of the crushing-floor, like smoke going up from the fireplace.
