'Impurity' in the Bible

This is how the priest is to present the sin offering to make atonement for the person being cleansed of his impurity. After this, he is to slaughter the whole burnt offering.

Anyone who comes in contact with a dead person (that is, with the corpse of a human being who has died), but who does not purify himself, defiles the LORD's tent. That person is to be eliminated from Israel, because the water of impurity wasn't sprinkled on him. He remains unclean and his uncleanness will remain with him.

"The person who is unclean but who doesn't purify himself is to be eliminated from contact with the assembly, since he has defiled the LORD's sanctuary and the water of impurity wasn't sprinkled on him. He is to be considered unclean

as a continuing reminder to them. Whoever sprinkles the water of impurity is to wash his clothes, and whoever comes in contact with the water of impurity is to remain unclean until evening.

or anything else that can survive a refiner's fire: You are to pass it through fire, after which it will be clean. Then it is to be purified with the water of impurity. Everything that cannot survive a refiner's fire is to be washed in water.

They've revealed the nakedness of their father in your midst. They've humiliated those among you who were unclean due to their impurity.

I'll sprinkle pure water on you all, and you'll be cleansed from your impurity and from all of your idols."
