18 "Are you so dull?" he asked. "Don't you see that nothing that enters a person from the outside can defile them? 19 For it doesn't go into their heart but into their stomach, and then out of the body." (In saying this, Jesus declared all foods clean.)
18 And he said to them, "Then are you also without understanding? Do you not see that whatever goes into a person from outside cannot defile him, 19 since it enters not his heart but his stomach, and is expelled?"
18 Jesus said, "Are you being willfully stupid? Don't you see that what you swallow can't contaminate you? 19 It doesn't enter your heart but your stomach, works its way through the intestines, and is finally flushed." (That took care of dietary quibbling; Jesus was saying that all foods are fit to eat.)
18 So He said to them, "Are you thus without understanding also? Do you not perceive that whatever enters a man from outside cannot defile him, 19 because it does not enter his heart but his stomach, and is eliminated, thus purifying all foods?"
18 "Don't you understand either?" he asked. "Can't you see that the food you put into your body cannot defile you? 19 Food doesn't go into your heart, but only passes through the stomach and then goes into the sewer." (By saying this, he declared that every kind of food is acceptable in God's eyes.)

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.
