If a thief be found breaking up, and be smitten that he die, there shall no blood
If the sun be risen upon him, there shall be blood shed for him; for he should make full restitution; if he have nothing, then he shall be sold for his theft.
If the theft be certainly found in his hand alive, whether it be ox, or ass, or sheep; he shall restore double.
If a man shall cause a field or vineyard to be eaten, and shall put in his beast, and shall feed in another man's field; of the best of his own field, and of the best of his own vineyard, shall he make restitution.
