(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 Leviticus 13:50.)

14:33-53 The leprosy in a house is unaccountable to us, as well as the leprosy in a garment; but now sin, where that reigns in a house, is a plague there, as it is in a heart. Masters of families should be aware, and afraid of the first appearance of sin in their families, and put it away, whatever it is. If the leprosy is got into the house, the infected part must be taken out. If it remain in the house, the whole must be pulled down. The owner had better be without a dwelling, than live in one that was infected. The leprosy of sin ruins families and churches. Thus sin is so interwoven with the human body, that it must be taken down by death.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.
