Isaiah 4

Seeing that latter days, Isaiah tells that -

"...the Lord will create upon every dwelling place of mount Zion, and upon her assemblies, a cloud and smoke by day, and the shining of a flaming fire by night: for upon all the glory shall be a defence."   (Isaiah 4:5)

The cloud of smoke by day and flaming fire by night was a sign to the Israelites that the Lord was with them.  Thus the promise of Isaiah is, in addition to Zion's assemblies, the Lord can be in our homes if we keep our covenants.
