1 Corinthians 9:9-11

MLV(i) 9 For it has been written in the Law of Moses, ‘You will not muzzle a threshing bull.’God does not care only for the bulls, does he? 10 Or does he certainly say it because of us? For it was written because of us, that the one who is plowing ought to plow in hope, and the one who is threshing ought to thresh in hope to partake of his hope.
11 If we sowed spiritual things to you, is it a big thing if we will be reaping your fleshly things?
