Isaiah 4:3-5

All who remain in Zion will be a holy people— those who survive the destruction of Jerusalem and are recorded among the living. The Lord will wash the filth from beautiful Zion and cleanse Jerusalem of its bloodstains with the hot breath of fiery judgment. Then the LORD will provide shade for Mount Zion and all who assemble there. He will provide a canopy of cloud during the day and smoke and flaming fire at night, covering the glorious land.
