1 Corinthians 9:7-9

Revised Standard Version Catholic Edition

⁷ Who serves as a soldier at his own expense? Who plants a vineyard without eating any of its fruit? Who tends a flock without getting some of the milk?

⁸ Do I say this on human authority? Does not the law say the same? ⁹ For it is written in the law of Moses, “You shall not muzzle an ox when it is treading out the grain.” Is it for oxen that God is concerned?
