'Midst' in the Bible

“Thus you shall separate the Israelites from their uncleanness, so that they do not die in their uncleanness by their defiling My tabernacle that is among them.”

So he shall make atonement for the Holy Place (Holy of Holies) because of the uncleanness and transgressions of the Israelites, for all their sins. He shall also do this for the Tent of Meeting which is among them in the midst of their uncleanness (impurities).
