John Wesley on Deuteronomy 13:14

Enquire - This is, meant of the magistrate, to whose office this properly belongs, and of whom he continues to speak in the same manner, thou, Deu 13:15,16. The Jewish writers say, the defection of a city is to be tried by the great sanhedrim. If it appear, that they are thrust away to idolatry, they send two learned men, to admonish them. If they repent, all is well: is not, all Israel must go up and execute this sentence. Tho' we do not find this law put in execution, in all the history of the Jewish church, yet for neglecting the execution of it on inferior cities, God himself by the army of the Chaldeans, executed it on Jerusalem, the head city, which was utterly destroyed, and lay in ruins for seventy years.
