Numbers 35:16-18

Amplified Bible, Classic Edition

¹⁶ But if he struck him down with an instrument of iron so that he died, he is a murderer; the murderer shall surely be put to death.

¹⁷ And if he struck him down by throwing a stone, by which a person may die, and he died, he is a murderer; the murderer shall surely be put to death.

¹⁸ Or if he struck him down with a weapon of wood in his hand, by which one may die, and he died, the offender is a murderer; he shall surely be put to death.
