• Mark 7:1-13
  Then the Pharisees and some of the scribes came together to Him, having come from Jerusalem. Now when they saw some of His disciples eat bread with defiled, that is, with unwashed hands, they found fault. For the Pharisees and all the Jews do not eat unless they wash their hands in a special way, holding the tradition of the elders. When they come from the marketplace, they do not eat unless they wash. And there are many other things which they have received and hold, like the washing of cups, pitchers, copper vessels, and couches. Then the Pharisees and scribes asked Him, “Why do Your disciples not walk according to the tradition of the elders, but eat bread with unwashed hands?” He answered and said to them, 'Well did Isaiah prophesy of you hypocrites, as it is written:
  ' This people honors Me with their lips,
  But their heart is far from Me.
  And in vain they worship Me,
  Teaching as doctrines the commandments of men.' For laying aside the commandment of God, you hold the tradition of men—the washing of pitchers and cups, and many other such things you do." He said to them, "All too well you reject the commandment of God, that you may keep your tradition. For Moses said, 'Honor your father and your mother'; and, 'He who curses father or mother, let him be put to death.' But you say, 'If a man says to his father or mother, 'Whatever profit you might have received from me is Corban"' (that is, a gift to God), then you no longer let him do anything for his father or his mother, making the word of God of no effect through your tradition which you have handed down. And many such things you do.'
   
• Matthew 15:9-14
  And in vain they worship Me,
  Teaching as doctrines the commandments of men."" When He had called the multitude to Himself, He said to them, “Hear and understand: Not what goes into the mouth defiles a man; but what comes out of the mouth, this defiles a man.” Then His disciples came and said to Him, “Do You know that the Pharisees were offended when they heard this saying?” But He answered and said, “Every plant which My heavenly Father has not planted will be uprooted. Let them alone. They are blind leaders of the blind. And if the blind leads the blind, both will fall into a ditch.'
   
• Romans 10:1-3
  Brethren, my heart's desire and prayer to God for Israel is that they may be saved. For I bear them witness that they have a zeal for God, but not according to knowledge. For they being ignorant of God's righteousness, and seeking to establish their own righteousness, have not submitted to the righteousness of God.
