What is the reason for the commandment to send the impure form the camp? Why are the laws of impurity in the camp placed at this intersection in the Book of Bemidbar? Was the distance meant to prevent accidental impurity in Holy Places? Or perhaps the prohibition indicates that there is inherent purity to the Camp of Israel? Apparently the order and structure of the Israeli Camp indicates that the Camp is a chariot for the Divine Presence, which requires an attention to the purity of the camp as a whole.
