5. create--The "new creation" needs as much God's creative omnipotence, as the material creation (2Co 4:6; Eph 2:10). So it shall be in the case of the Holy Jerusalem to come (Isa 65:17, 18).
      upon--The pillar of cloud stood over the tabernacle, as symbol of God's favor and presence (Ex 13:21, 22; Ps 91:1). Both on individual families ("every dwelling") and on the general sacred "assemblies" (Le 23:2). The "cloud" became a "fire" by night in order to be seen by the Lord's people.
      upon all the glory--"upon the glorious whole"; namely, the Lord's people and sanctuary [MAURER]. May it not mean, "Upon whatever the glory (the Shekinah spoken of in the previous clause) shall rest, there shall be a defense." The symbol of His presence shall ensure also safety. So it was to Israel against the Egyptians at the Red Sea (Ex 14:19, 20). So it shall be to literal Jerusalem hereafter (Zec 2:5). Also to the Church, the spiritual "Zion" (Isa 32:18; 33:15-17; Heb 12:22).
      tabernacle--Christ's body (Joh 1:14). "The word 'tabernacled' (Greek for 'dwelt') among us" (Joh 2:21; Heb 8:2). It is a "shadow from the heat" and "refuge from the storm" of divine wrath against man's sins (Isa 25:4). Heat and storms are violent in the East; so that a portable tent is a needful part of a traveller's outfit. Such shall be God's wrath hereafter, from which the "escaped of Israel" shall be sheltered by Jesus Christ (Isa 26:20, 21; 32:2).
      covert--answering to "defense" (Isa 4:5). The Hebrew for defense in Isa 4:5, is "covering"; the lid of the ark or mercy seat was named from the same Hebrew word, caphar; the propitiatory; for it, being sprinkled with blood by the high priest once a year, on the day of atonement, covered the people typically from wrath. Jesus Christ is the true Mercy Seat, on whom the Shekinah rested, the propitiatory, or atonement, beneath whom the law is kept, as it was literally within the ark, and man is covered from the storm. The redeemed Israel shall also be, by union with Him, a tabernacle for God's glory, which, unlike that in the wilderness, shall not be taken down (Isa 38:20).
