1 Corinthians 9:11-14 (King James Version)

 ¹¹If we have sown unto you spiritual things, is it a great thing if we shall reap your carnal things?

 ¹²If others be partakers of this power over you, are not we rather? Nevertheless we have not used this power; but suffer all things, lest we should hinder the gospel of Christ.

 ¹³Do ye not know that they which minister about holy things live of the things of the temple? and they which wait at the altar are partakers with the altar?

 ¹⁴Even so hath the Lord ordained that they which preach the gospel should live of the gospel.
