Exodus 21:17-20

17“Whoever curses his father or his mother or treats them contemptuously must be put to death.

18“If men quarrel and one strikes another with a stone or with his fist, and he does not die but is confined to bed,

19if he gets up and walks around leaning on his cane, then the one who struck him shall be left [physically] unpunished; he must only pay for his loss of time [at work], and the costs [of treatment and recuperation] until he is thoroughly healed.

20“If a man strikes his male or his female servant with a staff and the servant dies at his hand, he must be punished.
