Parallel
Numbers 5:7
Brenton's English Septuagint · Berean Standard Bible
[that person] shall confess the sin which he has committed, and shall make satisfaction for his trespass: he [shall pay] the principal, and shall add to it the fifth part, and shall make restoration to him against whom he has trespassed.
and must confess the sin he has committed. He must make full restitution, add a fifth to its value, and give all this to the one he has wronged.
