14 And he called the people to him again, and said to them, "Hear me, all of you, and understand: 15 there is nothing outside a man which by going into him can defile him; but the things which come out of a man are what defile him." 16 * [No text] 17 And when he had entered the house, and left the people, his disciples asked him about the parable. 18 And he said to them, "Then are you also without understanding? Do you not see that whatever goes into a man from outside cannot defile him, 19 since it enters, not his heart but his stomach, and so passes on?" (Thus he declared all foods clean.) 20 And he said, "What comes out of a man is what defiles a man. 21 For from within, out of the heart of man, come evil thoughts, fornication, theft, murder, adultery, 22 coveting, wickedness, deceit, licentiousness, envy, slander, pride, foolishness. 23 All these evil things come from within, and they defile a man."

Matthew Henry's Commentary on Mark 7:14-23

Commentary on Mark 7:14-23

(Read Mark 7:14-23)

Our wicked thoughts and affections, words and actions, defile us, and these only. As a corrupt fountain sends forth corrupt streams, so does a corrupt heart send forth corrupt reasonings, corrupt appetites and passions, and all the wicked words and actions that come from them. A spiritual understanding of the law of God, and a sense of the evil of sin, will cause a man to seek for the grace of the Holy Spirit, to keep down the evil thoughts and affections that work within.
