If a man causes a field or vineyard to be grazed over, or lets his beast loose and it feeds in another man's field, he shall make restitution from the best in his own field and in his own vineyard.

This man stole from his neighbor by letting his animal graze in the other's field. Since the animal ate indiscriminately, the restitution is not simply double what the animal ate, but the same amount of the best of the thief's crops. This is comparable to double restitution.
