Mark 7:14-19

14And he called to him the multitude again, and said unto them, Hear me all of you, and understand: 15there is nothing from without the man, that going into him can defile him; but the things which proceed out of the man are those that defile the man. 161 17And when he was entered into the house from the multitude, his disciples asked of him the parable. 18And he saith unto them, Are ye so without understanding also? Perceive ye not, that whatsoever from without goeth into the man, it cannot defile him; 19because it goeth not into his heart, but into his belly, and goeth out into the draught? This he said, making all meats clean.
