Theophylact of Ohrid, on 1Tim 5:18

“For the scripture saith: Thou shalt not muzzle the ox that treadeth out the corn: and, The labourer is worthy of his reward.”

“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 the expression "the laborer," the apostle shows that one must not seek comfort and rest. "The laborer is worthy of his reward," or food. By these words the apostle points to prosperity: for if the laborer is worthy of his reward, then how much more of food. But the one who does not labor is unworthy.”
