Albo téż to, o cokolwiek fałszywie przysiągł: zwróci to w pełnej wartości, a piątą część dołoży do tego; odda je zaś temu, czyje jest, w dzień pokuty swojej.

A robber with violence is not ordered to pay anything as fine (Lev. 5:24); the additional fifth part (of the value of the robbed goods) is only an atonement-offering for his perjury. The reason of this rule is to be found in the rare occurrence of robbery: theft is committed more frequently than robbery, for theft can be committed everywhere; robbery is not possible in towns, except with difficulty; besides, the thief takes things exposed as well as things hidden away; robbery applies only to things exposed; against robbery we can guard and defend ourselves; we cannot do so against theft; again, the robber is known, can be sought, and forced to return that which he has robbed, whilst the thief is not known. On account of all these circumstances the law fines the thief and not the robber.
