1 Corinthians 9:11-14

9:11 If we have sown unto you spiritual things, [is it] a great thing if we shall reap your carnal things? 9:12 If 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. 9:13 Do 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? 9:14 Even so hath the Lord ordained that they which preach the gospel should live of the gospel.
