Matthew 15:12-13

Then came his disciples Namely, when he was come into the house, apart from the multitude; and said unto him, Knowest thou that the Pharisees were offended, &c. The apostles, it seems, would gladly have conciliated the good-will of the Pharisees, thinking it might be of service to their cause; and thought it strange that their Master should say that which he knew would give them so much offence. Surely, they thought, if he had considered how provoking such a saying would be, he would not have uttered it. But he knew what he said, and to whom he said it, and what would be the effect of it; and he hereby teaches us, that though in indifferent things, we must be tender of giving offence, yet we must not, for fear of that, neglect to declare any truth, or enforce any duty. Truth must be owned, and duty must be done; and if any be offended, it is their own fault. Offence is not given, but taken. But he said, Every plant Or rather, plantation, as φυτεια is more properly rendered. As if he had said, Be they as angry as they will, you need not be afraid of them, for they and their doctrine shall perish together, being neither of them from God. Not only the corrupt opinions and superstitious practices of the Pharisees, but their sect, and way, and constitution were plants not of God's planting: the rules of their profession were not his institutions, but owed their original to pride and formality. And the people of the Jews in general, though planted a noble vine, were now become the degenerate plant of a strange vine. God disowned them as not of his planting.
