John Wesley on Micah 4:1

In the last days - Or, in the latter days, at the expiring of the seventy years captivity, near two hundred years from Micah's time, a type of the days of the Messiah's kingdom. The mountain - The mountain on which the temple stood, the type of the church of Christ. Established - Literally fulfilled when the second temple was built by the Jews. Spiritually, when Christ established his church by the preaching of the gospel.
