Mark 7: 5-8, 14-15, 20-23 NIV       
 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, but their hearts are far from me.
7 They worship me in vain; their teachings are merely human rules.’     8 You have let go of the commands of God and are holding on to human traditions.” 

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.” 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.”
