'Plowman' in the Bible

As when the one plows and breaks open the ground [and the soil scatters behind him],Our bones have been scattered at the mouth of Sheol [by the injustices of the wicked].

Doth the plowman plow all day to sow? doth he open and break the clods of his ground?

Behold, the days come, saith the LORD, that the plowman shall overtake the reaper, and the treader of grapes him that soweth seed; and the mountains shall drop sweet wine, and all the hills shall melt.

Or is He speaking altogether for our sake? Yes, for our sake it was written, because the plowman ought to plow in hope, and the thresher to thresh in hope of sharing the crops.
