36 And the priest shall command that they empty the house, before the priest goeth in to see the plague, that all that is in the house be not made unclean: and afterward the priest shall go in to see the house:

39 And the priest shall come again the seventh day, and shall look; and, behold, if the plague be spread in the walls of the house;
