Numbers 5:1-4

1 The Purity of the Camp
The Lord said to Moses,

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

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

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