Markos 7:2-4

Orthodox Jewish Bible

² And they had observed that some of his talmidim were eating their lechem with yadayim temeiot, that is, hands ritually unclean.

³ [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, see Ga 1:14).

⁴ 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.
