Context Reading
37He shall examine the plague; and behold, if the plague is in the walls of the house with hollow streaks, greenish or reddish, and it appears to be deeper than the wall, 38then the priest shall go out of the house to the door of the house, and shut up the house seven days. 39The priest shall come again on the seventh day, and look. If the plague has spread in the walls of the house, 40then the priest shall command that they take out the stones in which is the plague, and cast them into an unclean place outside of the city. 41He shall cause the inside of the house to be scraped all over. They shall pour out the mortar that they scraped off outside of the city into an unclean place.
