Numbers 5:2-4

Amplified Bible

² “Command the Israelites to send away from the camp every leper and everyone who has a discharge, and whoever is defiled [that is, ceremonially unclean] by [coming in contact with] the dead. ³ You shall send away both male and female; you shall send them outside the camp so that they will not defile their camp where I dwell in their midst.” ⁴ The Israelites did so, and sent them outside the camp; just as the Lord had said to Moses, so the Israelites did.
