1 Corinthians 9:5-10

Do we not have the right to take along a believing wife, as do the other apostles and the brothers of the Lord and Cephas? Or is it only Barnabas and I who have no right to refrain from working for a living? Who serves as a soldier at his own expense? Who plants a vineyard without eating any of its fruit? Or who tends a flock without getting some of the milk? Do I say these things on human authority? Does not the Law say the same? For it is written in the Law of Moses, “You shall not muzzle an ox when it treads out the grain.” Is it for oxen that God is concerned? Does he not certainly speak for our sake? It was written for our sake, because the plowman should plow in hope and the thresher thresh in hope of sharing in the crop.
