Mark 7:1-23 King James Version (KJV)
7 Then came together unto him the Pharisees, and certain of the scribes, which came from Jerusalem.
2 And when they saw some of his disciples eat bread with defiled, that is to say, with unwashen, hands, they found fault.
3 For the Pharisees, and all the Jews, except they wash their hands oft, eat not, holding the tradition of the elders.
4 And when they come from the market, except they wash, they eat not. And many other things there be, which they have received to hold, as the washing of cups, and pots, brasen vessels, and of tables.
5 Then the Pharisees and scribes asked him, Why walk not thy disciples according to the tradition of the elders, but eat bread with unwashen hands?
6 He answered and said unto them, Well hath Esaias prophesied of you hypocrites, as it is written, This people honoureth me with their lips, but their heart is far from me.
7 Howbeit in vain do they worship me, teaching for doctrines the commandments of men.
8 For laying aside the commandment of God, ye hold the tradition of men, as the washing of pots and cups: and many other such like things ye do.
9 And he said unto them, Full well ye reject the commandment of God, that ye may keep your own tradition.
10 For Moses said, Honour thy father and thy mother; and, Whoso curseth father or mother, let him die the death:
11 But ye say, If a man shall say to his father or mother, It is Corban, that is to say, a gift, by whatsoever thou mightest be profited by me; he shall be free.
12 And ye suffer him no more to do ought for his father or his mother;
13 Making the word of God of none effect through your tradition, which ye have delivered: and many such like things do ye.
14 And when he had called all the people unto him, he said unto them, Hearken unto me every one of you, and understand:
15 There is nothing from without a man, that entering into him can defile him: but the things which come out of him, those are they that defile the man.
16 If any man have ears to hear, let him hear.
17 And when he was entered into the house from the people, his disciples asked him concerning the parable.
18 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;
19 Because it entereth not into his heart, but into the belly, and goeth out into the draught, purging all meats?
20 And he said, That which cometh out of the man, that defileth the man.
21 For from within, out of the heart of men, proceed evil thoughts, adulteries, fornications, murders,
22 Thefts, covetousness, wickedness, deceit, lasciviousness, an evil eye, blasphemy, pride, foolishness:
23 All these evil things come from within, and defile the man.
Mark 7:1-23 New International Version (NIV)
That Which Defiles
7 The Pharisees and some of the teachers of the law who had come from Jerusalem gathered around Jesus 2 and saw some of his disciples eating food with hands that were defiled, that is, unwashed. 3 (The Pharisees and all the Jews do not eat unless they give their hands a ceremonial washing, holding to the tradition of the elders. 4 When they come from the marketplace they do not eat unless they wash. And they observe many other traditions, such as the washing of cups, pitchers and kettles.[a])
5 So the Pharisees and teachers of the law asked Jesus, “Why don’t your disciples live according to the tradition of the elders instead of eating their food with defiled hands?”
6 He replied, “Isaiah was right when he prophesied about you hypocrites; as it is written:
“‘These people honor me with their lips,
8 You have let go of the commands of God and are holding on to human traditions.”
9 And he continued, “You have a fine way of setting aside the commands of God in order to observe[c] your own traditions! 10 For Moses said, ‘Honor your father and mother,’[d] and, ‘Anyone who curses their father or mother is to be put to death.’[e] 11 But you say that if anyone declares that what might have been used to help their father or mother is Corban (that is, devoted to God)— 12 then you no longer let them do anything for their father or mother. 13 Thus you nullify the word of God by your tradition that you have handed down. And you do many things like that.”
14 Again Jesus called the crowd to him and said, “Listen to me, everyone, and understand this. 15 Nothing outside a person can defile them by going into them. Rather, it is what comes out of a person that defiles them.”  [f]
17 After he had left the crowd and entered the house, his disciples asked him about this parable. 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.)
20 He went on: “What comes out of a person is what defiles them. 21 For it is from within, out of a person’s heart, that evil thoughts come—sexual immorality, theft, murder, 22 adultery, greed, malice, deceit, lewdness, envy, slander, arrogance and folly. 23 All these evils come from inside and defile a person.”
