Matthew 15:10-20
10 After Jesus called the crowd to Him, He said, “Listen and understand this: 11 It is not what goes into the mouth of a man that defiles and dishonors him, but what comes out of the mouth, this defiles and dishonors him.”
12 Then the disciples came and said to Jesus, “Do You know that the Pharisees were offended when they heard you say this?”
13 He answered, “Every plant which My heavenly Father did not plant will be torn up by the roots. 14 Leave them alone; they are blind guides [leading blind followers]. If a blind man leads a blind man, both will fall into a pit.”
15 Peter asked Him, “Explain this parable [about what defiles a person] to us.”
16 And He said, “Are you still so dull [and unable to put things together]? 17 Do you not understand that whatever goes into the mouth passes into the stomach, and is eliminated? 18 But whatever [word] comes out of the mouth comes from the heart, and this is what defiles and dishonors the man. 19 For out of the heart come evil thoughts and plans, murders, adulteries, sexual immoralities, thefts, false testimonies, slanders (verbal abuse, irreverent speech, blaspheming). 20 These are the things which defile and dishonor the man; but eating with [ceremonially] unwashed hands does not defile the man.”
Mark 7:14-23
14 After He called the people to Him again, He began saying to them, “Listen [carefully] to Me, all of you, [hear] and understand [what I am saying]: 15 there is nothing outside a man [such as food] which by going into him can defile him [morally or spiritually]; but the things which come out of [the heart of] a man are what defile and dishonor him. 16 [If anyone has ears to hear, let him hear.”]
17 When Jesus had left the crowd and gone into the house, His disciples asked Him about the parable. 18 And He said to them, “Are you, too, so foolish and lacking in understanding? Do you not understand that whatever goes into the man from outside cannot defile and dishonor him, 19 since it does not enter his heart, but [only] his stomach, and [from there it] is eliminated?” (By this, He declared all foods ceremonially clean.) 20 And He said, “Whatever comes from [the heart of] a man, that is what defiles and dishonors him. 21 For from within, [that is] out the heart of men, come base and malevolent thoughts and schemes, acts of sexual immorality, thefts, murders, adulteries, 22 acts of greed and covetousness, wickedness, deceit, unrestrained conduct, envy and jealousy, slander and profanity, arrogance and self-righteousness and foolishness (poor judgment). 23 All these evil things [schemes and desires] come from within and defile and dishonor the man.”
