Markos 7:1-8

And, when they had come down from Yerushalayim, the Perushim and some of the Sofrim come together around Rebbe, Melech HaMoshiach, And they had observed that some of his talmidim were eating their lechem with yadayim temeiot, that is, hands ritually unclean. [For the Perushim, and indeed this was the Jewish minhag, do not eat without doing netilat yadayim (ritual of the washing of the hands) and also observing the Masoret HaZekenim (the Torah Shebal peh, Oral Torah). And when they come from [the] marketplace, unless they do so, they do not eat. And there are many other things which they have received in order to observe, such as the tevilah of cups and pitchers and copper pots.] And the Perushim and the Sofrim question Rebbe, Melech HaMoshiach, Why do your talmidim not follow the halakhah according to the Masoret HaZekenim, but eat their lechem with yadayim temeiot? And Rebbe, Melech HaMoshiach said to them, Yeshayah rightly gave a dvar nevuah of you tzevuim, as it has been written, HAAM HAZEH BISFATAV KIBDUNI VLIBO RIKHAK MIMENI (This people with [their] lips honor me, but their heart is removed far away from me). VATEHI YIRATAM OTI MITZVAT ANASHIM MELUMMADAH (And in vain do they worship me, teaching as doctrines the mitzvot of men.) Abandoning the mitzvat HASHEM, you are holding to the Masoret HaBnei Adam.
