'Plows' in the Bible

The charge was one pin for plows, mattocks, three pronged forks, and axes, or for setting the goads.

Just as one plows and breaks up the earth, our bones are scattered near the entrance to the place of the dead.

Does he who plows for sowing plow all the time? Does he keep on breaking up and harrowing his field?

Isn't he really speaking for our benefit? Yes, this was written for our benefit, because the one who plows should plow in hope, and the one who threshes should thresh in hope of sharing in the crop.
