For God said, 'Honor your father and mother'1 and 'Anyone who curses his father or mother must be put to death.'2
References for Matthew 15:4
But you say that if a man says to his father or mother, 'Whatever help you might otherwise have received from me is a gift devoted to God,'
he is not to 'honor his father ' with it. Thus you nullify the word of God for the sake of your tradition.
References for Matthew 15:6
