'Impurities' in the Bible

He shall make atonement for the holy place, because of the impurities of the sons of Israel and because of their transgressions in regard to all their sins; and thus he shall do for the tent of meeting which abides with them in the midst of their impurities.

With his finger he shall sprinkle some of the blood on it seven times and cleanse it, and from the impurities of the sons of Israel consecrate it.
