The prophet reproves Jerusalem, and all her guides and rulers, for their obstinate perseverance in impiety, notwithstanding all the warnings and corrections which they had received from God, Zep 3:1-7. They are encouraged, however, after they shall have been chastised for their idolatry, and cured of it, to look for mercy and restoration, Zep 3:8-13; and exited to hymns of joy at the glorious prospect, Zep 3:14-17. After which the prophet concludes with large promises of favor and prosperity in the days of the Messiah, Zep 3:18-20. We take this extensive view of the concluding verses of this chapter, because an apostle has expressly assured us that in Every prophetical book of the Old Testament Scriptures are confined predictions relative to the Gospel dispensation. See Act 3:24.
