Many therefore of his disciples, &c.— As our Lord had a great number of disciples at large, who often attended his ministry, and made a profession of his name; so many of them, whose hearts were not right with him, were highly offended at what he had said about his being the bread that came down from heaven, and about the necessity of eating him in order to their living by him: they who still took these things in a literal sense, thought it a monstrous doctrine: they who took them in a figurative sense, as Christ explained them, thought that he blasphemously assumed to himself a divine original and operation; and they who knew not what construction to put upon his words, thought there was something so mysterious in them, that no man in his senses could receive them. But if they had been humble and childlike, and had really sought spiritual blessings for their souls, they would have understood our Lord perfectly well.
