a group of Pharisees and some scribes from Jerusalem came to meet Jesus. they saw that some of his disciples eating with unclean hands, that is not washed hand. because the Pharisees as those other Jews do not eat if not washing hands first. because they hold on their ancestral customs, and if they returned from the market they do not eat before cleaning their body. many more heritage they hold, for example it wash bowls, jugs and copper fittings. Hence the Pharisees and experts of the law asked him: "why your disciples not obey our ancestors, eat with defiled hand?" he said to them: "true Isaiah say about you, hypocrites! for is written: this people glorify me with their lips, but their heart is far from me. vain they worship me, cause they are teaching is the human command. god command you reject to obey human law. "
jesus also said to them, really clever you override the command of Allah, that you may keep your tradition. because Moses had said: 'Honor your father and your mother! and, anyone who speaks evil to father or mother must die. but you said: if a man say to his father or his mother: what is with me, which can be used to you, already used to the victim - that is offering to the god - then you no longer let him do anything for his father or his mother. and the word of God of none effect by your tradition that you follow it. and many other things like that you do.
then Jesus called the crowd again and said to them: "you all, listen to me and mark. anything from outside, which goes into the man, can not defile him, but what came out of someone, that is can defile." (Whoever have ears to hear let him hear!)
after he entered a house to get away from the crowds, his disciples asked him about the meaning of this parable. then he replied: "Do you also can not understand it? do you not know that anything from outside that enters the person can not defile him, because not enter his heart but into his stomach, then dumped in the toilet?" this he declared all foods kosher. he said again. "what comes out of someone, that is defile him, because from inside, from the heart proceed evil thoughts, fornication, theft, murder, adultery, greed, evil, cunning, lust, envy, blasphemy, arrogance, ignorance. all these evil things come from heart and defile a man.
