'Ceremonial' in the Bible

and they had seen that some of His disciples ate their bread with [ceremonially] impure hands, that is, unwashed [and defiled according to Jewish religious ritual].

(For the Pharisees and all of the Jews do not eat unless they carefully wash their hands, holding firmly to the traditions of the elders;

since it does not enter his heart, but [only] his stomach, and [from there it] is eliminated?” (By this, He declared all foods ceremonially clean.)

Now there were six stone waterpots set there for the Jewish custom of purification (ceremonial washing), containing twenty or thirty gallons each.
