1 Corinthians 9:7-9

King James Version

⁷ Who 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?

⁸ Say I these things as a man? or saith not the law the same also?

⁹ For it is written in the law of Moses, thou shalt not muzzle the mouth of the ox that treadeth out the corn. Doth God take care for oxen?
