Num Numbers, chapter Book of Numbers, chapter 35
Likewise, if anyone maliciously pushes another or intentionally throws an object at him and kills him, Deu 19:11or if in hostility he strikes him with his hand and he dies, the one who struck him must surely be put to death; he is a murderer. When the avenger of blood finds the murderer, he is to kill him.Deu 19:12
