1 Corinthians 9:10-13

or saith he it assuredly for our sake? Yea, for our sake it was written: because he that ploweth ought to plow in hope, and he that thresheth, to thresh in hope of partaking. If we sowed unto you spiritual things, is it a great matter if we shall reap your carnal things? If others partake of this right over you, do not we yet more? Nevertheless we did not use this right; but we bear all things, that we may cause no hindrance to the gospel of Christ. 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?
