Numbers 35:19

¹⁷  And if he smite him with throwing a stone, wherewith he may die, and he die, he is a murderer: the murderer shall surely be put to death.

¹⁸  Or if he smite him with an hand weapon of wood, wherewith he may die, and he die, he is a murderer: the murderer shall surely be put to death.

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.
