Then the priest shall go out of the house to the door of the house, and shut up the house seven days:
Then the priest shall go out of the house to the door of the house,…. Thereby signifying that it was not fit to be inhabited, and there standing to see it shut up, as follows:
and shut up the house seven days: to observe what alteration would be made in that time, and which would sooner be discovered in a house uninhabited.

(38) Shut up the house seven days.On finding these symptoms, the priest is to put the house in quarantine for seven days, in order to see what alteration will take place during this interval, adopting the same treatment as in the case of leprous garments. (See Lev. 13:50.)
