Numbers 5:1-4 - Rules Concerning Those Unclean
1 And Jehovah spake unto Moses, saying, 2 Command the children of Israel, that they put out of the camp every leper, and every one that hath an issue, and whosoever is unclean by the dead: 3 both male and female shall ye put out, without the camp shall ye put them; that they defile not their camp, in the midst whereof I dwell. 4 And the children of Israel did so, and put them out without the camp; as Jehovah spake unto Moses, so did the children of Israel.
