Digest of Biblical Civil Law

If a thief comes to his senses and voluntarily seeks to make restitution, he is to add a fifth part to what property (Exo. 22:1-15) ¬he stole when he returns it (Lev. 5:14-16; 6:1-5; 22:14; Num. 5:5-8). Thus, if a man steals a sheep, he has an incentive to return it before he is caught; the penalty is less.
