Therefore, before the priest enters in, the things in the house are pure; but after he has entered in, from that time forth they are all impure. And yet the contrary would have been natural, that when a man thoroughly purified and perfect, who is in the habit of offering up prayers and purifications, and sacrifices for all the people come into a house, all that is therein would be improved by his presence, and would become pure from having been impure; but now they do not even remain in the same condition as before, but they are brought into a worse state by the arrival of the priest.
