Numbers 35:16-21New International Version (NIV)

¹⁶ “‘If anyone strikes someone a fatal blow with an iron object, that person is a murderer; the murderer is to be put to death. ¹⁷ Or if anyone is holding a stone and strikes someone a fatal blow with it, that person is a murderer; the murderer is to be put to death. ¹⁸ Or if anyone is holding a wooden object and strikes someone a fatal blow with it, that person is a murderer; the murderer is to be put to death. ¹⁹ The avenger of blood shall put the murderer to death; when the avenger comes upon the murderer, the avenger shall put the murderer to death. ²⁰ If anyone with malice aforethought shoves another or throws something at them intentionally so that they die ²¹ or if out of enmity one person hits another with their fist so that the other dies, that person is to be put to death; that person is a murderer. The avenger of blood shall put the murderer to death when they meet.
