7 Bible Verses about Contamination

Or if a soul touches any unclean thing, whether a dead body of an unclean beast, or a dead body of unclean cattle, or the dead body of unclean swarming things, and if it is hidden from him that he is unclean and guilty--

Whoever touches the dead body of any man that is dead, and does not purify himself, defiles the tabernacle of Jehovah. And that soul shall be cut off from Israel. Because the water of separation was not sprinkled upon him, he shall be unclean. His uncleanness is still upon him.

Turn! Turn! Go out from there! Touch not the unclean. Go out of her midst; purify yourself, bearers of the vessels of Jehovah.

And Jehovah spoke to Moses and Aaron, saying, When you come into the land of Canaan which I give you for a possession, and I put the plague of leprosy in a house in the land of your possession, and if he that owns the house shall come and tell the priest, saying, A plague is seen by me in the house;read more.
then the priest shall command that they empty the house before the priest goes to see the plague, so that all that is in the house may not become unclean. And afterwards the priest shall go in to see the house. 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, then the priest shall go out of the house to the door of the house, and shut up the house seven days. And the priest shall come again the seventh day and shall look. And behold, if the plague has spread in the walls of the house, then the priest shall command that they take away the stones in which the plague is, and they shall throw them into an unclean place outside the city. And he shall cause the house to be scraped inside all around, and they shall pour out the dust that they scrape off outside the city in an unclean place. And they shall take other stones and put them in the place of those stones. And he shall take other mortar and shall plaster the house. And if the plague comes again and breaks out in the house after he has taken away the stones and after he has scraped the house, and after it is plastered, then the priest shall come and look. And behold, if the plague has spread in the house, it is a fretting leprosy in the house. It is unclean. And he shall break down the house, the stones of it, and the timber of it, and all the mortar of the house, and he shall carry them out of the city into an unclean place. And he that goes into the house all the days that it is shut up shall be unclean until the evening. And he that lies in the house shall wash his clothes. And he that eats in the house shall wash his clothes.
