Mark 7:4

“Woe to you, scribes and Pharisees, hypocrites! For you clean the outside of the cup and of the dish, but inside they are full of robbery and self-indulgence.

“You blind Pharisee, first clean the inside of the cup and of the dish, so that the outside of it may become clean also.

But when the Pharisee saw it, he marveled that He had not first ceremonially washed before the meal.

Now there were six stone water jars set there for the Jewish custom of purification, containing two or three measures each.

since they relate only to food and drink and various washings, requirements for the body imposed until a time of reformation.
