Numbers 35:16 Meaning and Commentary

Numbers 35:16

And if he smite him with an instrument of iron, so that he
die
As with an hatchet, hammer, sword, knife, &c.

he is a murderer;
the instrument used by him, and with which he smote, shows that he had a bad design, and intended to kill, or he would never have smitten a man with such an instrument:

the murderer shall surely be put to death;
be condemned to death, and be executed, by the order of the civil magistrate, according to the law in ( Genesis 9:6 ) and not be allowed the benefit of a city of refuge.

Numbers 35:16 In-Context

14 Select three cities across the Jordan and three cities in the land of Canaan to be cities of refuge.
15 These six cities will serve as a refuge for the Israelites and for the foreigner or temporary resident among them, so that anyone who kills a person unintentionally may flee there.
16 "If anyone strikes a person with an iron object and death results, he is a murderer; the murderer must be put to death.
17 If a man has in his hand a stone capable of causing death and strikes another man and he dies, the murderer must be put to death.
18 If a man has in his hand a wooden object capable of causing death and he dies, the murderer must be put to death.
