Mark 7:13
Thus you nullify the word of God by your tradition that you have handed down. And you do many things like that — the nullification of God's word is the structural accusation: the tradition does not supplement the Torah but replaces it in practice. You nullify (akyrountes, making without authority, making void) the word of God by your tradition. And you do many things like that — the Corban example is representative, not unique. The pattern is systemic, not occasional.
