And he saith unto them, Are ye so without understanding also? Do ye not perceive, that whatsoever thing from without entereth into the man, it cannot defile him; because it entereth not into his heart, but into the belly, and goeth out into the draught, purging all meats? And he said, That which cometh out of the man, that defileth the man. For from within, out of the heart of men, proceed evil thoughts, adulteries, fornications, murders, thefts, covetousness, wickedness, deceit, lasciviousness, an evil eye, blasphemy, pride, foolishness: all these evil things come from within, and defile the man.
[KJV (1611)]

“You are no more intelligent than the others,” Jesus said to them. “Don't you understand? Nothing that goes into you from the outside can really make you unclean, because it does not go into your heart but into your stomach and then goes on out of the body.” (In saying this, Jesus declared that all foods are fit to be eaten.)
And he went on to say, “It is what comes out of you that makes you unclean. For from the inside, from your heart, come the evil ideas which lead you to do immoral things, to rob, kill, commit adultery, be greedy, and do all sorts of evil things; deceit, indecency, jealousy, slander, pride, and folly -- all these evil things come from inside you and make you unclean.”
[GNT (1966)]

Jesus said to them, 'Even you -- don't you understand? Can't you see that nothing that goes into someone from outside can make that person unclean, because it goes not into the heart but into the stomach and passes into the sewer? And he went on, 'It is what comes out of someone that makes that person unclean. For it is from within, from the heart, that evil intentions emerge: fornication, theft, murder, adultery, avarice, malice, deceit, indecency, envy, slander, pride, folly. All these evil things come from within and make a person unclean.'
[NJB (1985)]

Jesus said to them, “Don’t you understand either? Don’t you know that nothing from the outside that enters a person has the power to contaminate? That’s because it doesn’t enter into the heart but into the stomach, and it goes out into the sewer.” By saying this, Jesus declared that no food could contaminate a person in God’s sight. “It’s what comes out of a person that contaminates someone in God’s sight,” he said. “It’s from the inside, from the human heart, that evil thoughts come: sexual sins, thefts, murders, adultery, greed, evil actions, deceit, unrestrained immorality, envy, insults, arrogance, and foolishness. All these evil things come from the inside and contaminate a person in God’s sight.”
[CEB (2011)]

He said to them, “So, are you also without understanding? Do you not see that whatever goes into a person from outside cannot defile, since it enters not the heart but the stomach and goes out into the sewer?” (Thus he declared all foods clean.) And he said, “It is what comes out of a person that defiles. For it is from within, from the human heart, that evil intentions come: sexual immorality, theft, murder, adultery, avarice, wickedness, deceit, debauchery, envy, slander, pride, folly. All these evil things come from within, and they defile a person.”
[NRSV (2021 ed.)]

Not that which goeth into the mouth defileth a man; but that which cometh out of the mouth, this defileth a man.
[KJV (1611)]

What goes into the mouth does not make a man unclean; it is what comes out of the mouth that makes him unclean.
[JB (1966)]

It is not what goes into your mouth that makes you ritually unclean; rather, what comes out of it makes you unclean.
[GNT (1966)]

It’s not what goes into the mouth that contaminates a person in God’s sight. It’s what comes out of the mouth that contaminates the person.
[CEB (2011)]

It is not what goes into the mouth that defiles a person, but it is what comes out of the mouth that defiles.
