Exodus 21:12-15

12“1He who strikes someone so that he dies shall certainly be put to death. 132Yet 3if he did not lie in wait for him, but 4God caused him to fall into his hand, then I will appoint you a place to which he may flee. 145If, however, someone is enraged against his neighbor, so as to kill him in a cunning way, you are to take him even from My altar, to be put to death.

15“And one who strikes his father or his mother shall certainly be put to death.
