What does Isaiah 4:5 mean?

then the Lord will create a cloud by day and smoke and a bright, flaming fire by night over every part of Mount Zion and over everyone gathered there. His glory will cover everything like a shelter. Isaiah 4:5 - Modern Text Bible

(After the cleansing, God will protect and be present with his people, just like he did in the wilderness with the cloud and fire. His presence will be obvious and will cover everyone who belongs to him.)
