Numbers 5:6-7

6Speak to the people of Israel, aWhen a man or woman commits any of the sins that people commit by breaking faith with the Lord, and that person realizes his guilt, 7 bhe shall confess his sin that he has committed.
Hebrew they shall confess their sin that they have committed
dAnd he shall make full restitution for his wrong, adding a fifth to it and giving it to him to whom he did the wrong.
