Êxodo 22:4 Referências da Mishná: Mishnah Bava Kamma & Mishnah Gittin

There are four primary causes of injury: the ox and the pit and the crop-destroying beast and fire. [The distinctive feature of] the ox is not like [that of] the crop-destroying beast, nor is [the distinctive feature of] either of these, which are alive, like [that of] fire, which is not alive; nor is [the distinctive feature of] any of these, whose way it is to go forth and do injury, like [that of] the pit, whose way it is not to go forth and do injury. What they have in common is that it is their way to do injury and that you are responsible for caring over them; and if one of them did injury whoever [is responsible] for the injury must make restitution [to the damaged party] with the best of his land.

How is the tooth [of a beast] an attested danger to eat that which it is fit to consume? A beast is an attested danger to eat fruit and vegetables. [If however] it ate clothing or utensils [the owner] pays only half damages. When does this apply? [This applies] in the domain of the damaged party But if it was within the public domain, the owner is not liable. If [the beast] benefited, [the owner] pays what it benefited. How does [the owner] pay what [the animal] benefited? [If it ate] from the middle of the marketplace, [the owner] pays what [the animal] benefited. [If it ate] from the sides of the marketplace, [the owner] pays for the damage [the animal] did. [If it ate] from in front of the store [the owner] pays for what [the animal] benefited. [If it ate] from inside the store [the owner] pays for the damage [the animal] did.

Damages are paid out of [property of] the best quality; A creditor is paid out of land of medium quality, And a ketubah is paid out of land of the poorest quality. Rabbi Meir says that a ketubah is also paid out of medium quality land.
