1 Corinthians 9:9-10

For it is written in the Law of Moses, “YOU SHALL NOT MUZZLE THE OX WHILE HE IS THRESHING.” God is not concerned about oxen, is He? 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.
