'Contagion' in the Bible
"When clothing becomes infected with a contagion whether the clothing is wool or linen
if the contagion is greenish or reddish in the clothing, leather, woven material, knitted material, or with any article containing leather, it's a fungal infection and is to be shown to the priest.
"The priest is to examine the contagion and isolate the clothing for seven days.
The priest is to examine the contagion on the seventh day. If the infection has spread on the clothing, in the woven material, the knitted material, or in the leather, no matter the purpose for which the leather material had been manufactured, the contagion is a chronic fungal infection. It's unclean.
"Incinerate the clothing, the woven material, the knitted material (whether wool or linen), or any of the leather articles on which the contagion is found, because it's a chronic fungal infection. It is to be incinerated.
then the priest is to command that they wash whatever has the contagion and then isolate it for seven days a second time.
Then the priest is to examine it after the contagion has been washed. If the contagion hasn't changed in appearance, even though the contagion hasn't spread, it's unclean. Incinerate it. It's a fungal infection, especially if the infection is on its exposed side.
"If the priest examines the item and determines that the contagion has become dull after it has been washed, tear it away from the garment, leather, woven material, or knitted material.
But if it recurs on the clothing (whether woven or knitted material) or on any article made of leather, it's a breakout, so incinerate it with fire wherever the contagion is found.
Then the clothing (whether it is woven or knitted material) or any article made of leather that you've washed, if the contagion has been removed from it and it's washed a second time, then it's clean.
"When you enter the land of Canaan that I'm about to give you as your own possession, and if I put a contagion in a house in the land that you possess,
then the owner of the house is to approach the priest and tell him, "There appears to be a contagion in the house.'
"The priest is to command that the house be cleared before he comes to examine the contagion so that not everything in the house becomes unclean. After this, the priest is to enter the house and examine it.
He is to determine if the contagion is indeed on the walls of the house, with greenish or reddish streaks, and to determine if it appears to be deeper than the surface of the wall.
He is to return after seven days to examine it. If the contagion has spread to the walls of the house,
"If the contagion returns and spreads throughout the house after the stones have been removed, after the house has been scraped out, and after it has been re-coated,
and the priest comes, undertakes an examination, and determines that the contagion has spread in the house, it's a chronic fungal infection in the house. It's unclean.
"But if the priest comes in to conduct an examination and determines that the contagion has not spread throughout the house after the house has been repaired, then the priest may declare the house clean, because the contagion has been cleansed.
"This is the law for every contagion of infectious skin disease and scabs,
