Thematic Bible: Of the labors of ministers

For it is written in the law of Moses, Thou shalt not muzzle the mouth of the ox that treads out the grain. Does God take care for oxen? Or does he say it altogether for our sakes? For our sakes, no doubt, this is written: that he that plows should plow in hope, and that he that threshes in hope should be partaker of his hope.
