[If] the bull of a person of sound mind gores the bull of a deaf-mute, a mentally deranged person, or a minor, [its owner] is lia-ble. But [if the bull] of a deaf-mute, a mentally deranged person, or a minor gores the bull of a person of sound mind, [its owner] is exempt.  [If] the bull of a deaf-mute, a mentally deranged person, or a minor gores, the court appoints for them an administrator, and they forewarn them in the presence of the administrator.  [If] the deaf-mute gains his senses, the mentally deranged person becomes sane, or the minor becomes of age, [the bull] reverts to its status of tam; this is R' Me-ir's view. R' Yose says: It remains in its present state.  A bull from the arena is not liable to death, as it is said (Exodus 21:28): If [a bull] gores, but not that it should be made to gore.
