What should a ‘leper’ do?
He shall wear torn clothes, let his hair hang loose, cover his upper lip and cry out, “Unclean, unclean!”
Indeed, he shall remain unclean as long as he has the disease. He is unclean. He shall live alone.
And his dwelling shall be outside the camp (Lev 13.45-46).
The tent of meeting, which symbolized the physical presence of YHWH, was once set up outside the camp as well after the Israelites made a golden calf of themselves (Exo 33.7). It symbolized how YHWH was rejected by his own people.
Well, YHWH is not only the Rejected One, but he is also the One with the Rejected.
