Isaiah 4:4-5

4When the Lord has washed away the [moral] filth of the daughters of Zion and has cleansed the bloodstains of Jerusalem from her midst, by the spirit of judgment and by the spirit of burning,

5then the Lord will create over the entire site of Mount Zion and over her assemblies, a cloud by day, smoke, and the brightness of a flaming fire by night; for over all the glory and brilliance will be a canopy [a defense, a covering of His divine love and protection].
