Kehillah in Corinth I 9:7-9

Orthodox Jewish Bible

⁷ Whoever heard of someone serving as a chaiyal (soldier) but having to pay his own wages for doing so? Who plants a kerem (vineyard) but does not eat the p’ri hakerem? And who serves as a ro’eh (shepherd) over a flock and of the cholov (milk) of the flock does not partake? [Devarim 20:6; Mishle 27:18]

⁸ Do I say this according to the dvar haBnei Adam? Or does not the Torah say these things?

⁹ For, in the Torah of Moshe [Rabbenu] it has been written, LO TACHSOM SHOR BEDISHO ("You shall not muzzle an ox treading grain" DEVARIM 25:4). Surely it is not for oxen that Hashem is concerned.
