Numbers 5:1-3

American Standard Version

5 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.
