Numbers 5:2-4

5:2 “Command the Israelites to expel from the camp every leper, everyone who has a discharge, and whoever becomes defiled by a corpse. 5:3 You must expel both men and women; you must put them outside the camp, so that they will not defile their camps, among which I live.” 5:4 So the Israelites did so, and expelled them outside the camp. As the Lord had spoken to Moses, so the Israelites did.
