'Impurity' in the Bible

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

In thee have they uncovered their fathers nakedness; in thee have they humbled her that was unclean in her impurity.

Son of man, when the house of Israel dwelt 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.
