Numbers 5:1-4 - Rules Concerning Those Unclean
1 The LORD spoke to Moses, saying, 2 "Command the people of Israel that they put out of the camp everyone who is leprous or has a discharge and everyone who is unclean through contact with the dead. 3 You shall put out both male and female, putting them outside the camp, that they may not defile their camp, in the midst of which I dwell." 4 And the people of Israel did so, and put them outside the camp; as the LORD said to Moses, so the people of Israel did.
