Matthew 15:13

But he answered and said, Every plant, which my heavenly Father hath not planted, shall be rooted up--They are offended, are they? Heed it not: their corrupt teaching is already doomed: the garden of the Lord upon earth, too long cumbered with their presence, shall yet be purged of them and their accursed system: yea, and whatsoever is not of the planting of My heavenly Father, the great Husbandman (Joh 15:1), shall share the same fate.

In this chapter, we have our Lord Jesus, as the great Prophet teaching, as the great Physician healing, and as the great Shepherd of the sheep feeding; as the Father of spirits instructing them; as the Conqueror of Satan dispossessing him; and as concerned for the bodies of his people, providing for them. Here is, I. Christ's discourse with the scribes and Pharisees about human traditions and injunctions (Mat 15:1-9). II. His discourse with the multitude, and with his disciples, concerning the things that defile a man (Mat 15:10-20). III. His casting of the devil out of the woman of Canaan's daughter (Mat 15:21-28). IV. His healing of all that were brought to him (Mat 15:29-31). V. His feeding of four thousand men, with seven loaves and a few little fishes (Mat 15:32-39).

15:13 not planted by my heavenly Father: These Pharisees did not belong to the true people of God (see 3:9-12; Isa 5:1-7; Jer 45:4). They will be uprooted at the final judgment (see Matt 3:10; 8:12).
