Numbers 5:5-7

5And Jehovah spoke to Moses, saying,

6Speak unto the children of Israel, When a man or woman shall commit any of all the sins of man to work unfaithfulness against Jehovah, and that soul is guilty,

7then they shall confess their sin which they have done; and he shall recompense his trespass according to the principal thereof, and shall add unto it the fifth part thereof, and give it unto him against whom he hath trespassed.
