Numbers 35:19-21

New Revised Standard Version, Anglicised

¹⁹ The avenger of blood is the one who shall put the murderer to death; when they meet, the avenger of blood shall execute the sentence. ²⁰ Likewise, if someone pushes another from hatred, or hurls something at another, lying in wait, and death ensues, ²¹ or in enmity strikes another with the hand, and death ensues, then the one who struck the blow shall be put to death; that person is a murderer; the avenger of blood shall put the murderer to death when they meet.
