St. Paul's First Letter to the Corinthians 9:2-12

BRETHREN, you are the seal of my apostleship in the Lord. This is my defense to those who would examine me. Do we not have the right to our food and drink? Do we not have the right to be accompanied by a wife, as 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? Who tends a flock without getting some of the milk? Do I say this 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 is treading out the grain." Is it for oxen that God is concerned? Does he not speak entirely for our sake? It was written for our sake, because the plowman should plow in hope and the thresher thresh in hope of a share in the crop. If we have sown spiritual good among you, is it too much if we reap your material benefits? If others share this rightful claim upon you, do not we still more? Nevertheless, we have not made use of this right, but we endure anything rather than put an obstacle in the way of the gospel of Christ.
