1 Corinthians 9:1-10

Am I not free [unrestrained and exempt from any obligation]? Am I not an apostle? Have I not seen Jesus our [risen] Lord [in person]? Are you not [the result and proof of] my work in the Lord? If I am not [considered] an apostle to others, at least I am one to you; for you are the seal and the certificate and the living evidence of my apostleship in the Lord [confirming and authenticating it]. This is my defense to those who would put me on trial and interrogate me [concerning my authority as an apostle]: Have we not the right to our food and drink [at the expense of the churches]? Have we not the right to take along with us a believing wife, as do the rest of the apostles and the Lord’s brothers and Cephas (Peter)? Or is it only Barnabas and I who have no right to stop doing manual labor [in order to support our ministry]? [Consider this:] Who at any time serves as a soldier at his own expense? Who plants a vineyard and does not eat its fruit? Or who tends a flock and does not use the milk of the flock? Do I say these things only from a man’s perspective? Does the Law not endorse the same principles? For it is written in the Law of Moses, “YOU SHALL NOT MUZZLE AN OX WHILE IT IS TREADING OUT THE GRAIN [to keep it from eating the grain].” Is it [only] for oxen that God cares? [Deut 25:4] Or does He speak entirely for our sake? Yes, it was written for our sake: The plowman ought to plow in hope, and the thresher to thresh in hope of sharing the harvest.
