Isaiah 4:3-5

Those who are left in Zion, who remain in Jerusalem, will be called holy, all who are recorded among the living in Jerusalem. The Lord will wash away the filth of the women of Zion; he will cleanse the bloodstains from Jerusalem by a spirit of judgment and a spirit of fire. Then the LORD will create over all of Mount Zion and over those who assemble there a cloud of smoke by day and a glow of flaming fire by night; over everything the glory will be a canopy.
