10 He then called the crowd together and said, "Listen, and take this to heart. 11 It's not what you swallow that pollutes your life, but what you vomit up." 12 Later his disciples came and told him, "Did you know how upset the Pharisees were when they heard what you said?" 13 Jesus shrugged it off. "Every tree that wasn't planted by my Father in heaven will be pulled up by its roots. 14 Forget them. They are blind men leading blind men. When a blind man leads a blind man, they both end up in the ditch." 15 Peter said, "I don't get it. Put it in plain language." 16 Jesus replied, "You too? Are you being willfully stupid? 17 Don't you know that anything that is swallowed works its way through the intestines and is finally defecated? 18 But what comes out of the mouth gets its start in the heart. 19 It's from the heart that we vomit up evil arguments, murders, adulteries, fornications, thefts, lies, and cussing. 20 That's what pollutes. Eating or not eating certain foods, washing or not washing your hands - that's neither here nor there." Healing the People
Matthew Henry's Commentary on Matthew 15:10-20
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.
