10 And having called to [him] the crowd, he said to them, Hear and understand: 11 Not what enters into the mouth defiles the man; but what goes forth out of the mouth, this defiles the man. 12 Then his disciples, coming up, said to him, Dost thou know that the Pharisees, having heard this word, have been offended? 13 But he answering said, Every plant which my heavenly Father has not planted shall be rooted up. 14 Leave them alone; they are blind leaders of blind: but if blind lead blind, both will fall into a ditch. 15 And Peter answering said to him, Expound to us this parable. 16 But he said, Are ye also still without intelligence? 17 Do ye not yet apprehend, that everything that enters into the mouth finds its way into the belly, and is cast forth into the draught? 18 but the things which go forth out of the mouth come out of the heart, and those defile man. 19 For out of the heart come forth evil thoughts, murders, adulteries, fornications, thefts, false witnessings, blasphemies; 20 these are the things which defile man; but the eating with unwashen hands does not defile man.

Commentary on Matthew 15:10-20
(Read Matthew 15:10-20)
Christ shows that the defilement they ought to fear, was not from what entered their mouths as food, but from what came out of their mouths, which showed the wickedness of their hearts. Nothing will last in the soul but the regenerating graces of the Holy Spirit; and nothing should be admitted into the church but what is from above; therefore, whoever is offended by a plain, seasonable declaration of the truth, we should not be troubled at it. The disciples ask to be better taught as to this matter. Where a weak head doubts concerning any word of Christ, an upright heart and a willing mind seek for instruction. It is the heart that is desperately wicked, Jeremiah 17:9, for there is no sin in word or deed, which was not first in the heart. They all come out of the man, and are fruits of that wickedness which is in the heart, and is wrought there. When Christ teaches, he will show men the deceitfulness and wickedness of their own hearts; he will teach them to humble themselves, and to seek to be cleansed in the Fountain opened for sin and uncleanness.
