The reparation offering is the only class that arrives attached to a sum of money. Leviticus prescribes a ram without blemish, valued in silver by a fixed standard, and alongside it the restitution of whatever was wrongly taken plus a further fifth of its value paid to the injured party. The offering does not substitute for the repayment and the repayment does not substitute for the offering. Both are required, in that order, and the sequence is the point: the altar does not settle a debt that is still outstanding to a person.
The occasions fall into two groups that do not obviously belong together. The first is sacrilege, the unwitting use of something that belongs to the sanctuary, where the fifth is paid to the sanctuary itself. The second is a group of property offences aggravated by a false oath: denying a deposit or a pledge, keeping something found and swearing it was never seen, or defrauding a neighbour and lying about it. The second group is the striking one, because these are deliberate wrongs, and the Priestly system otherwise deals only with what was done unwittingly. The bridge is the false oath, which drags a private fraud into the sanctuary's jurisdiction by invoking the divine name over it.
A third case covers the person who suspects a trespass but cannot establish that one occurred, and brings the ram anyway. The class also closes two purification processes that have nothing to do with property at all: that of the person healed of the skin affliction, whose blood is placed on the ear, thumb and toe, and that of the nazirite whose vow has been interrupted by a death.
