Mark 7:2-4

2and seeing some of his disciples eat bread with defiled, that is, unwashed, hands,

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),
