'Impurity' in the Bible

"'If a woman has a discharge, and her discharge in her flesh is blood, she shall be in her impurity seven days: and whoever touches her shall be unclean until the evening.

"'Everything that she lies on in her impurity shall be unclean. Everything also that she sits on shall be unclean.

"'If a man takes his brother's wife, it is an impurity: he has uncovered his brother's nakedness; they shall be childless.

"A man who is clean shall gather up the ashes of the heifer, and lay them up outside of the camp in a clean place; and it shall be kept for the congregation of the children of Israel for a water for impurity: it is a sin offering.

Whoever touches a dead person, the body of a man who has died, and doesn't purify himself, defiles the tabernacle of Yahweh; and that soul shall be cut off from Israel: because the water for impurity was not sprinkled on him, he shall be unclean; his uncleanness is yet on him.

But the man who shall be unclean, and shall not purify himself, that soul shall be cut off from the midst of the assembly, because he has defiled the sanctuary of Yahweh: the water for impurity has not been sprinkled on him; he is unclean.

It shall be a perpetual statute to them: and he who sprinkles the water for impurity shall wash his clothes, and he who touches the water for impurity shall be unclean until evening.

everything that may withstand the fire, you shall make to go through the fire, and it shall be clean; nevertheless it shall be purified with the water for impurity: and all that doesn't withstand the fire you shall make to go through the water.

and has not eaten on the mountains, neither has lifted up his eyes to the idols of the house of Israel, neither has defiled his neighbor's wife, neither has come near to a woman in her impurity,

In you have they uncovered their fathers' nakedness; in you have they humbled her who was unclean in her impurity.

Son of man, when the house of Israel lived in their own land, they defiled it by their way and by their doings: their way before me was as the uncleanness of a woman in her impurity.

It will come to pass in that day, says Yahweh of Armies, that I will cut off the names of the idols out of the land, and they will be remembered no more. I will also cause the prophets and the spirit of impurity to pass out of the land.
