The man
 who is said to have driven another away by violence has many pleas of defence allowed him,
 (and if he can prove any one of them to the satisfaction of the judge, then, even if he
 confesses that he drove him out by violence, he must gain his cause,) either that he who has
 been driven out was not the owner, or that he had got possession from him himself by violence,
 or by stealth, or as a present. Our ancestors left so many pleas of defence, by which he might
 gain his cause, even to the man who confessed himself guilty of violence.
