Numbers 5:3-7

Both male and female shall ye put out, without the camp shall ye put them; that they defile not their camps, in the midst whereof I dwell.

And the children of Israel did so, and put them out without the camp: as the LORD spake unto Moses, so did the children of Israel.

And the LORD spake unto Moses, saying,

Speak unto the children of Israel, When a man or woman shall commit any sin that men commit, to do a trespass against the LORD, and that person be guilty;

Then they shall confess their sin which they have done: and he shall recompense his trespass with the principal thereof, and add unto it the fifth part thereof, and give it unto him against whom he hath trespassed.
