'Tread' in the Bible

With the hoofs of his horses shall he tread down all your streets; he shall kill your people with the sword; and the pillars of your strength shall go down to the ground.

Does it seem a small thing to you to have fed on the good pasture, but you must tread down with your feet the residue of your pasture? and to have drunk of the clear waters, but you must foul the residue with your feet?
