Matthew 15:4-6

15:4 For God said, ‘Honor your father and mother’ and ‘Whoever insults his father or mother must be put to death.’ 15:5 But you say, ‘If someone tells his father or mother, “Whatever help you would have received from me is given to God,” 15:6 he does not need to honor his father.’ You have nullified the word of God on account of your tradition.

Mark 7:11-13

7:11 But you say that if anyone tells his father or mother, ‘Whatever help you would have received from me is corban’ (that is, a gift for God), 7:12 then you no longer permit him to do anything for his father or mother. 7:13 Thus you nullify the word of God by your tradition that you have handed down. And you do many things like this.”
