Numbers 5:2  (King James Version)
Command the children of Israel, that they put out of the camp every leper, and every one that hath an issue, and whosoever is defiled by the dead:

put out of the camp
The camp of Israel being now formed, with the sanctuary of God in the centre, orders were given that the lepers and unclean persons should be excluded from the camp, according to the laws given at different times on these subjects. See the Marginal References
) This expulsion was founded, 1. On a purely physical reason; for the diseases were contagious, and therefore there was a necessity of putting those afflicted with them apart, that the infection might not be communicated
2. There was also a spiritual reason: the camp was the habitation of God; and therefore, in honour of Him who had thus condescended to dwell with them, nothing impure should be permitted to remain
3. Further, there was a typical reason; for the camp was the emblem of the church, where nothing that is defiled should enter, and in which nothing that is unholy should be tolerated.
