'Impurities' in the Bible

Thus he shall make atonement for the sanctuary from the {Israelites}' impurities and from their transgressions for all their sins; and so he must do for [the] tent of assembly, which dwells with them in the midst of their impurities.

And he shall spatter {some of} the blood on it seven times with his finger, and he shall cleanse it and consecrate it from the {Israelites}' impurities.
