Deuteronomy 17:7 Meaning and Commentary

Deuteronomy 17:7

The hands of the witnesses shall be first upon him to put him
to death
Of everyone of them, as Aben Ezra; they were to cast the first stone at him, which would be a further trial and confirmation of their testimony; for if they readily and without reluctance first began the stoning of the idolater, it would not only show their zeal for the honour of the divine Being, but an unconsciousness of guilt in their testimony, and be an encouragement to others to proceed with safety:

and afterwards the hands of all the people;
should be employed in taking up stones, and casting at him until he was dead:

so thou shall put the evil away from among you;
both the evil man and the evil committed by him, which by this means would be prevented from spreading, seeing by his death others would be deterred from following his example; as well as the evil of punishment, which otherwise would have come upon the nation, had they connived at so gross an iniquity.

Deuteronomy 17:7 In-Context

5 then the man or woman who has committed such an evil act must be taken to the gates of the town and stoned to death.

6 But never put a person to death on the testimony of only one witness. There must always be two or three witnesses.

7 The witnesses must throw the first stones, and then all the people may join in. In this way, you will purge the evil from among you.

8 “Suppose a case arises in a local court that is too hard for you to decide—for instance, whether someone is guilty of murder or only of manslaughter, or a difficult lawsuit, or a case involving different kinds of assault. Take such legal cases to the place the LORD your God will choose,

9 and present them to the Levitical priests or the judge on duty at that time. They will hear the case and declare the verdict.
