Exodus 21:12-14

New Revised Standard Version, Anglicised Catholic Edition

The Law concerning Violence

¹² Whoever strikes a person mortally shall be put to death. ¹³ If it was not premeditated, but came about by an act of God, then I will appoint for you a place to which the killer may flee. ¹⁴ But if someone wilfully attacks and kills another by treachery, you shall take the killer from my altar for execution.
