Exodus 21:12; Exodus 21:14; Exodus 21:20

12 nWhoever strikes a man so that he dies shall be put to death.

14 But if a man willfully attacks another to kill him by cunning, qyou shall take him from my altar, that he may die.

20 When a man strikes his slave, male or female, with a rod and the slave dies under his hand, he shall be avenged.
