1 Corinthians 9:13-23

Know ye not that they that minister about sacred things eat of the things of the temple, and they that wait upon the altar have their portion with the altar? Even so did the Lord ordain that they that proclaim the gospel should live of the gospel. But I have used none of these things: and I write not these things that it may be so done in my case; for it were good for me rather to die, than that any man should make my glorying void. For if I preach the gospel, I have nothing to glory of; for necessity is laid upon me; for woe is unto me, if I preach not the gospel. For if I do this of mine own will, I have a reward: but if not of mine own will, I have a stewardship intrusted to me. What then is my reward? That, when I preach the gospel, I may make the gospel without charge, so as not to use to the full my right in the gospel. For though I was free from all men, I brought myself under bondage to all, that I might gain the more. And to the Jews I became as a Jew, that I might gain Jews; to them that are under the law, as under the law, not being myself under the law, that I might gain them that are under the law; to them that are without law, as without law, not being without law to God, but under law to Christ, that I might gain them that are without law. To the weak I became weak, that I might gain the weak: I am become all things to all men, that I may by all means save some. And I do all things for the gospel’s sake, that I may be a joint partaker thereof.
