7 Who ever serves in the army at his own expense? Who plants a vineyard and does not eat its fruit? Who tends a flock and does not consume its milk? 8 Am I saying these things only on the basis of common sense, or does the law not say this as well? 9 For it is written in the law of Moses, “Do not muzzle an ox while it is treading out the grain.” God is not concerned here about oxen, is he? 10 Or is he not surely speaking for our benefit? It was written for us, because the one plowing and threshing ought to work in hope of enjoying the harvest. 11 If we sowed spiritual blessings among you, is it too much to reap material things from you? 12 If others receive this right from you, are we not more deserving?But we have not made use of this right. Instead we endure everything so that we may not be a hindrance to the gospel of Christ.

The mishna teaches that Rabbi Yosei, son of Rabbi Yehuda, says: A laborer may not eat unless he performs labor with his hands and with his feet. The Gemara asks: What is the reasoning of Rabbi Yosei, son of Rabbi Yehuda? The Gemara explains: This halakha is like that of a threshing ox; just as one is not required to let an ox feed unless it is performing labor with its hands and with its feet, as it uses all four of its legs to thresh, so too a laborer is not entitled to eat unless he is performing labor with his hands and with his feet.
