Numbers 5:7 Meaning and Commentary

Numbers 5:7

Then they shall confess their sin which they have done
The form of which confession, according to Fagius, was, O Lord, I am guilty of death, I have deserved to be stoned for this sin, or to be strangled for this trespass, or to be burnt for this crime

and he shall recompense his trespass with the principal thereof, and
add unto it the fifth [part] thereof;
paying the whole of whatsoever he had in any manner defrauded his neighbour of, to which he was to add a fifth part of that; that is, as Aben Ezra interprets it, it he confesses of himself, but if there are witnesses of it he must add two fifths, and some say a fifth of a fifth:

and give [it] unto [him] against whom he hath trespassed;
as a satisfaction for the injury done him.

Numbers 5:7 In-Context

5 And Jehovah speaketh unto Moses, saying,
6 `Speak unto the sons of Israel, Man or woman, when they do any of the sins of man, by committing a trespass against Jehovah, and that person [is] guilty,
7 and they have confessed their sin which they have done, then he hath restored his guilt in its principal, and its fifth is adding to it, and hath given [it] to him in reference to whom he hath been guilty.
8 `And if the man have no redeemer to restore the guilt to, the guilt which is restored [is] Jehovah's, the priest's, apart from the ram of the atonements, whereby he maketh atonement for him.
9 `And every heave-offering of all the holy things of the sons of Israel, which they bring near to the priest, becometh his;
