Deuteronomy 19:12
Then the elders of his city shall send and fetch him thence, and deliver him into the hand of the avenger of blood, that he may die.
Then the elders of his city shall send and fetch him thence,.... The Targum of Jonathan is,
"the wise men of his city,''
the sanhedrim, or court of judicature, or at least the civil magistrates of that city, to which such a murderer belonged, had a power to send to the city of refuge whither he was fled, and demand the delivering of him up to them, that his case might be tried before them, and it might appear whether he was a proper person to receive the benefit of the city of refuge or not, and if not, to pass sentence of death upon him, and see it executed as follows:
and deliver him into the hand of the avenger of blood, that he may die; that is, after the examination and trial of him, and when he is found guilty, and sentence is passed upon him, then he was to be delivered into the hands of the avenger of blood, to be the executioner of that sentence.
