'Impurities' in the Bible

So he is to make atonement for the holy place from the impurities of the Israelites and from their transgressions with regard to all their sins, and thus he is to do for the Meeting Tent which resides with them in the midst of their impurities.

Then he is to sprinkle on it some of the blood with his finger seven times, and cleanse and consecrate it from the impurities of the Israelites.
