The protection of property is obviously a matter of great importance in the Avesta. The utility of dogs is frequently mentioned, which protect flocks and villages from thieves and wolves. Theft is looked on as especially wicked, because the thief leads a roving life, eats raw and unprepared food, and carries on his evil work in the darkness.[433] In regard to contracts the Vendidad distinguishes six kinds, according as they are concluded by word, by the pledge of hands, and are concerned with the value of a head of small cattle, a beast of draught, a man (_i.e._ a slave), and a piece of land. Anyone who violates the first kind is to receive 300 blows with the rod, and 300 with the whip, and the punishment increases in the violation of the other kinds up to 1000 stripes with both instruments.[434] To check injury of the person the Vendidad lays down the rule, that anyone who lifts up his weapon against a man without beating him, is to receive twice five stripes the first time, and twice two hundred on the seventh occasion of committing the offence, if he has not expiated the preceding six offences; if he has expiated them, the measure of the first offence is dealt out on each occasion. Anyone who attacks another not in anger but with malice, is to be punished with twice fifteen, and on the sixth occasion with 200 stripes, in case he has not expiated the former offences. Anyone who inflicts a wound on another, is punished the first time with twice thirty, the fifth time with twice two hundred stripes. The same punishment is inflicted on a man who breaks the bones of another, if he does not expiate the offence. If the wound proves fatal, he is to be punished with twice ninety stripes, and on a second offence with twice two hundred.[435]
