1 Corinthians 9:12-18

ISV(i) 12 If others enjoy this right over you, don’t we have a stronger claim? But we did not use this right. On the contrary, we tolerate everything in order not to put an obstacle in the way of the gospel of the Messiah.
13 You know that those who work in the Temple get their food from the Temple and that those who serve at the altar get their share of its offerings, don’t you? 14 In the same way, the Lord has ordered that those who proclaim the gospel should make their living from the gospel.
15 But I have not used any of these rights, and I’m not writing this so that they may be applied in my case. I would rather die than let anyone deprive me of my reason for boasting. 16 For if I preach the gospel, I have nothing to boast about, for this obligation has been entrusted to me. How terrible it would be for me if I didn’t preach the gospel! 17 For if I preach voluntarily, I get a reward, but if I am unwilling to do it, I am still entrusted with that obligation. 18 What, then, is my reward? It is to be able to preach the gospel free of charge, and so I never resort to demanding my rights when I’m preaching the gospel.
