Numbers 35:19-21

Lexham English Bible

¹⁹ The blood avenger himself will put the killer to death; he must put him to death when meeting him. ²⁰ If he shoves him in hatred, or he throws something at him with intention, and he dies, ²¹ or if he hits him in hostility with his hand, and he dies, the one that struck him will put to death the killer when meeting him.
