Leviticus 14:37 WBT

³⁵  And he that owneth the house shall come and tell the priest, saying, it seemeth to me [there is] as it were a plague in the house:

³⁶  Then the priest shall command that they empty the house, before the priest shall enter to see the plague, that all that [is] in the house may not be made unclean; and afterward the priest shall go in to see the house:

³⁷  And he shall look on the plague, and behold, [if] the plague [is] in the walls of the house, with hollow streaks, greenish, or reddish, which in sight [are] lower than the wall;

³⁸  Then the priest shall go out of the house to the door of the house, and shut up the house seven days:

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