1 Corinthians 9:11-14

If we sowed spiritual things in you, is it too much if we reap material things from you? If others share the right over you, do we not more? Nevertheless, we did not use this right, but we endure all things so that we will cause no hindrance to the gospel of Christ. Do you not know that those who perform sacred services eat the food of the temple, and those who attend regularly to the altar have their share from the altar? So also the Lord directed those who proclaim the gospel to get their living from the gospel.
