Mark 7:2-4

2 And when they had seen some of his disciples eat bread with common, that is, with unwashed hands, they found fault.

3 For the Pharisees and all the Jews eat not without often washing their hands, holding the tradition of the ancients.

4 And when they come from the market, unless they be washed, they eat not: and many other things there are that have been delivered to them to observe, the washings of cups and of pots and of brazen vessels and of beds.
