Bible: Ex. 21:12-14
“Whoever strikes someone 2 so that he dies 3 must surely be put to death. 4 21:13 But if he does not do it with premeditation, 5 but it happens by accident, 6 then I will appoint for you a place where he may flee. 21:14 But if a man willfully attacks his neighbor to kill him cunningly, 7 you will take him even from my altar that he may die.
