1 Corinthians 9:3-10

3This is my defense to those who would put me on trial and interrogate me [concerning my authority as an apostle]:

4Have we not the right to our food and drink [at the expense of the churches]?

5Have 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)?

6Or is it only Barnabas and I who have no right to stop doing manual labor [in order to support our ministry]?

7[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?

8Do I say these things only from a man’s perspective? Does the Law not endorse the same principles?

9For 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?

10Or 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.
