Leviticus 14:34-38

34When ye come into the land of Canaan, which I give to you for a possession, and I put a leprous plague in a house of the land of your possession,

35then he whose house it is shall come and tell the priest, saying, It seemeth to me like a plague in the house;

36and the priest shall command that they empty the house before the priest go into it to see the plague, that all that is in the house be not made unclean; and afterwards the priest shall go in to see the house.

37And when he looketh on the plague, and behold, the plague is in the walls of the house, greenish or reddish hollows, and their look is deeper than the surface of the wall,

38then the priest shall go out of the house to the entrance of the house, and shut up the house seven days.
