Mark 7:3-4

3(for the Pharisees and all the Jews, unless they wash their hands diligently, do not eat, holding what has been delivered by the ancients;

4and [on coming] from the market-place, unless they are washed, they do not eat; and there are many other things which they have received to hold, the washing of cups and vessels, and brazen utensils, and couches),
