Numbers 35:18-21 New American Standard Bible (NASB)

18. Or if he struck him with a wooden object in the hand, by which he might die, and as a result he died, he is a murderer; the murderer shall surely be put to death.

19. The blood avenger himself shall put the murderer to death; he shall put him to death when he meets him.

20. If he pushed him of hatred, or threw something at him lying in wait and as a result he died,

21. or if he struck him down with his hand in enmity, and as a result he died, the one who struck him shall surely be put to death, he is a murderer; the blood avenger shall put the murderer to death when he meets him.
