'Impurities' in the Bible

He will purify the most holy place in this way for all their sins because of the Israelites’ impurities and rebellious acts. He will do the same for the tent of meeting that remains among them, because it is surrounded by their impurities.

He is to sprinkle some of the blood on it with his finger seven times to cleanse and set it apart from the Israelites’ impurities.
