'Ritually' in the Bible

(For the Pharisees, in fact all the Jews, will not eat unless they wash their hands ritually, keeping the tradition of the elders.

Then the Pharisees and the scribes asked Him, “Why don’t Your disciples live according to the tradition of the elders, instead of eating bread with ritually unclean hands?”

and while I was doing this, some Jews from Asia found me ritually purified in the temple, without a crowd and without any uproar.
