Num Numbers, chapter Book of Numbers, chapter 35

But if he thrust him of hatred, or hurl at him by laying of wait, that he die;Deu 19:11

Or in hatred (being an enemy) strike him with his hand, that he die: he that struck [him] shall surely be put to death; [for] he [is] a murderer: the revenger of blood shall slay the murderer, when he meets him.Deu 19:12
