Theophylact of Ohrid — as excerpted in the Catena Aurea on John 4:31-34

“From the question of the disciples, Hath any man brought Him ought to eat, we may infer that our Lord was accustomed to receive food from others, when it was offered Him: not that He who giveth food to all flesh, (Ps. 146.) needed any assistance; but He received it, that they who gave it might obtain their reward, and that poverty thenceforth might not blush, nor the support of others be esteemed a disgrace. It is proper and necessary that teachers should depend on others to provide them with food, in order that, being free from all other cares, they may attend the more to the ministry of the word.”
