Deuteronomy 19:11; Exodus 21:12; Exodus 21:14

11 But if anyone hates his neighbor and lies in wait for him and attacks him xand strikes him fatally so that he dies, and he flees into one of these cities,

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.
