1 Corinthians 9:13-18

13Do ye not know that they who labour [at] sacred things eat of the [offerings offered in the] temple; they that attend at the altar partake with the altar?

14So also the Lord has ordained to those that announce the glad tidings to live of the glad tidings.

15But I have used none of these things. Now I have not written these things that it should be thus in my case; for [it were] good for me rather to die than that any one should make vain my boast.

16For if I announce the glad tidings, I have nothing to boast of; for a necessity is laid upon me; for it is woe to me if I should not announce the glad tidings.

17For if I do this voluntarily, I have a reward; but if not of my own will, I am entrusted with an administration.

18What is the reward then that I have? That in announcing the glad tidings I make the glad tidings costless [to others], so as not to have made use, as belonging to me, of my right in [announcing] the glad tidings.
