Numbers 5:5-7

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.
