'Treading' in the Bible

For in the Law of Moses it is written, "You must not muzzle an ox while it is treading out the grain." God is not only concerned about oxen, is he?

or because of us by all means doth He say it? yes, because of us it was written, because in hope ought the plower to plow, and he who is treading ought of his hope to partake in hope.
