Exodus 21:12-14 New American Bible, Revised Edition (NABRE)

12. Whoever strikes someone a mortal blow must be put to death.

13. However, regarding the one who did not hunt another down, but God caused death to happen by his hand, I will set apart for you a place to which that one may flee.

14. But when someone kills a neighbor after maliciously scheming to do so, you must take him even from my altar and put him to death.
