1 Corinthians 9:12-18

If others share in this rightful claim over you, do not we even more? However, we did not exercise this right, but we put up with everything so that we will not hinder [the spread of] the good news of Christ. Do you not know that those who officiate in the sacred services of the temple eat from the temple [offerings of meat and bread] and those who regularly attend the altar have their share from the [offerings brought to the] altar? [Deut 18:1] So also [on the same principle] the Lord directed those who preach the gospel to get their living from the gospel. But I have used none of these privileges, nor am I writing this [to suggest] that any such provision be made for me now. For it would be better for me to die than to have anyone deprive me of my boast [in this matter of financial support]. For if I [merely] preach the gospel, I have nothing to boast about, for I am compelled [that is, absolutely obligated to do it]. Woe to me if I do not preach the good news [of salvation]! For if I do this work of my own free will, then I have a reward; but if it is not of my will [but by God’s choosing], I have been entrusted with a [sacred] stewardship. What then is my reward? [Just this:] that, when I preach the gospel, I may offer the gospel without charge [to everyone], so as not to take advantage of my rights [as a preacher and apostle] in [preaching] the gospel.
