Numbers 5:8 (KJV)

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.

But if the man have no kinsman to recompense the trespass unto, let the trespass be recompensed unto the Lord, even to the priest; beside the ram of the atonement, whereby an atonement shall be made for him.

And every offering of all the holy things of the children of Israel, which they bring unto the priest, shall be his.

And every man’s hallowed things shall be his: whatsoever any man giveth the priest, it shall be his.
