Numbers 5:1-4
Unclean people
1 The Lord said to Moses, 2 ‘Speak to the Israelites. They must send any person with a disease of the skin away from the camp. Or somebody may have a disease that causes pus to come out of his body. Any person like that is not clean. Anyone who has touched a dead person is also not clean. Send those people out of the camp too. 3 Do this with both men and women. Send them out of the camp. They must not make the camp unclean, because that is where I live among the people.’
4 The Israelites did what the Lord had said to Moses. They sent those people outside the camp.
