Numbers 5:1-4 - Rules Concerning Those Unclean
1 And LORD spoke to Moses, saying, 2 Command the sons of Israel, that they put out of the camp every leper, and every man who has an issue, and whoever is unclean about life. 3 Ye shall put out both male and female. Ye shall put them outside the camp, that they not defile their camp, in the midst of which I dwell. 4 And the sons of Israel did so, and put them outside the camp. As LORD spoke to Moses, so did the sons of Israel.
