Thematic Bible: What proceeds from the heart

After Jesus called the crowd to Him, He said to them, "Hear and understand. "It is not what enters into the mouth that defiles the man, but what proceeds out of the mouth, this defiles the man."

After He called the crowd to Him again, He began saying to them, "Listen to Me, all of you, and understand: there is nothing outside the man which can defile him if it goes into him; but the things which proceed out of the man are what defile the man. ["If anyone has ears to hear, let him hear."] read more.
When he had left the crowd and entered the house, His disciples questioned Him about the parable. And He said to them, "Are you so lacking in understanding also? Do you not understand that whatever goes into the man from outside cannot defile him, because it does not go into his heart, but into his stomach, and is eliminated?" (Thus He declared all foods clean.) And He was saying, "That which proceeds out of the man, that is what defiles the man. "For from within, out of the heart of men, proceed the evil thoughts, fornications, thefts, murders, adulteries, deeds of coveting and wickedness, as well as deceit, sensuality, envy, slander, pride and foolishness. "All these evil things proceed from within and defile the man."
