1 Corinthians 9:7-11

Who at any time serves as a soldier at his own expense? Who plants a vineyard and does not eat its fruit? Or who tends a flock and does not consume some of the milk of the flock?

I am not just asserting these things according to human judgment, am I? Or does the Law not say these things as well?

For it is written in the Law of Moses: “You shall not muzzle the ox while it is threshing.” God is not concerned about oxen, is He?

Or is He speaking entirely for our sake? Yes, it was written for our sake, because the plowman ought to plow in hope, and the thresher to thresh in hope of sharing in the crops.

If we sowed spiritual things in you, is it too much if we reap material things from you?
