Numbers 35:19-21

King James Version

¹⁹ The revenger of blood himself shall slay the murderer: when he meeteth him, he shall slay him.

²⁰ But if he thrust him of hatred, or hurl at him by laying of wait, that he die;

²¹ Or in enmity smite him with his hand, that he die: he that smote him shall surely be put to death; for he is a murderer: the revenger of blood shall slay the murderer, when he meeteth him.
