Numbers 5:1-4

The LORD said to Moses, “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. Send away male and female alike; send them outside the camp so they will not defile their camp, where I dwell among them.” The Israelites did so; they sent them outside the camp. They did just as the LORD had instructed Moses.
