Exodus 21:17-20

17Anyone who curses1 his father or mother must surely be put to death.2

18If men are quarreling and one strikes the other with a stone or a fist, and he does not die but is confined to bed, 19then the one who struck him shall go unpunished, as long as the other can get up and walk around outside with his staff. Nevertheless, he must compensate the man for his lost work and see that he is completely healed.

20If a man strikes his manservant or maidservant with a rod, and the servant dies by his hand, he shall surely be punished.
