[If] one strikes his father or his mother, but does not inflict a wound upon them, or [if] one wounds another on Yom Kippur, he is liable for all of them.  [If] one wounds a Jewish bondman, he is liable for all of them except loss of time when he is his. [If] one wounds a gentile slave belonging to others, he is liable for all of them. R' Yehudah says: Slaves have no [indemnity for] disgrace.
