Numbers 5:2-4

2“Command the Israelites to send away from the camp anyone who has a defiling skin disease or a discharge of any kind, or who is ceremonially unclean because of a dead body.

3Send away male and female alike; send them outside the camp so they will not defile their camp, where I dwell among them.”

4The Israelites did so; they sent them outside the camp. They did just as the Lord had instructed Moses.
