1 Corinthians 9:3-10

3Mine answer to them that do examine me is this, 4Have we not right to eat and to drink? 5Have we not right to lead about a sister, a wife, as well as other apostles, and as the brethren of the Lord, and Cephas? 6Or I only and Barnabas, have not we right to forbear working? 7Who goeth a warfare any time at his own charges? who planteth a vineyard, and eateth not of the fruit thereof? or who feedeth a flock, and eateth not of the milk of the flock? 8Say I these things as a man? or saith not the law the same also? 9For it is written in the law of Moses, Thou shalt not muzzle the mouth of the ox that treadeth out the grain. Doth God take care for oxen? 10Or saith he it altogether for our sakes? For our sakes, no doubt, this is written: that he that ploweth should plow in hope; and that he that thresheth in hope should be partaker of his hope.
