II. That there shall be a wonderful reformation in Jerusalem, and religion, in the power of it, shall prevail and flourish there. "Jerusalem, that has dealt treacherously both with God and man, shall become so famous for fidelity and honesty that it shall be called and known by the name of a city of truth, and the inhabitants of it shall be called children that will not lie. The faithful city has become a harlot (Isa. i. 21), but shall now become a faithful city again, faithful to the God of Israel and to the worship of him only." This was fulfilled; for the Jews after the captivity, though there was much amiss among them, were never guilty of idolatry. Jerusalem shall be called the mountain of the Lord of hosts, owning him and owned by him, and therefore the holy mountain, cleared from idols and consecrated to God, and not, as it had been, the mount of corruption, 2 Kings xxiii. 13. Note, The city of God ought to be a city of truth and the mountain of the Lord of hosts a holy mountain. Those that profess religion, and relation to God, must study to adorn their profession by all instances of godliness and honesty.
