1 Timothy 5:18

The elders who rule well are to be considered worthy of double honor, especially those who labor in preaching and teaching. For the Scripture says, "Do not muzzle an ox while it is treading out the grain," and, "The worker deserves his wages." Who then …

He alleges the Law, he alleges the words of Christ, both agreeing herein. For the Law says, "Thou shall not muzzle the ox that treadeth out the corn." See how he would have the teacher labor! For there is not, indeed there is not, any other labor such as his. But this is from the Law. But how does he quote from Christ? "The laborer is worthy of his reward." Let us not then look only to the reward, but to the terms of the commandment. "The laborer," he says, "is worthy of his reward." So that if any one lives in sloth and luxury, he is unworthy of it. Unless he is as the ox treading out the corn, and bearing the yoke, in spite of heat and thorns, and ceases not till he has carried the corn into the granary, he is not worthy.

And it should be noted what is added: "The laborer is worthy of his hire," because the very food for sustenance is already part of the wages of the work, so that here the reward from the labor of preaching may begin, which is perfected there in the vision of truth. In this matter it should be considered that two rewards are owed to our one work: one on the way, the other in the homeland; one which sustains us in labor, another which recompenses us in the resurrection. Therefore the reward which is received in the present ought to accomplish this in us: that we may strive more vigorously toward the subsequent reward. Therefore every preacher should not preach in order to receive a reward in this time, but should receive a reward in order to continue preaching. For whoever preaches in order to receive here a reward of either praise or gift, without doubt deprives himself of the eternal reward.

Then when he says, for the Scripture says, he proves his statement with two authorities: one is used in the mystical sense and the other in the literal sense, at the laborer is worthy of his reward. He says, therefore, for the Scripture says, namely, …

The apostle brings forward testimonies—one from the law, and another testimony of Christ. In both, observe what labor is required of the teacher. Threshing is the most arduous labor: and the teacher likewise must be prepared for every kind of toil, hardship, and grief. By …
