“Should a man steal an ox or a sheep and slaughter it or sell it, five cattle he shall pay for the ox and four sheep for the sheep.” Why four times for the sheep and five for the ox? R. Yohanan explains that to steal a sheep one must carry it, not so an ox, which is just led away. Because of the additional effort and humiliation that a sheep thief endures, his punishment is reduced. Why four or fivefold the value of the animal? This crime was so easy to get away with, explains ShaDaL, that to prevent it from happening a strong disincentive was needed.
