Isaiah 4:5

"And Jehovah creates over every spot of Mount Zion, and over its festal assemblies, a cloud by day, and smoke, and the shining of flaming fire by night: for over all the glory comes a canopy." Just as Jehovah guided and shielded Israel in the days of the redemption from Egypt in a smoke-cloud by day and a fire-cloud by night, which either moved in front like a pillar, or floated above them as a roof (Num 14:14, etc.), the perpetuation of His presence at Sinai (Exo 19:9, Exo 19:16.); so would Jehovah in like manner shield the Israel of the final redemption, which would no longer need the pillar of cloud since its wanderings would be over, but only the cloudy covering; and such a covering Jehovah would create, as the praet. consec. וּברא) ("and He creates") distinctly affirms. The verb bârâh always denotes a divine and miraculous production, having its commencement in time; for even the natural is also supernatural in its first institution by God. In the case before us, however, the reference is to a fresh manifestation of His gracious presence, exalted above the present course of nature. This manifestation would consist by day in "a cloud," and as the hendiadys "cloud and smoke" (i.e., cloud in form and smoke in substance) distinctly affirms, a smoke-cloud, not a watery cloud, like those which ordinarily cover the sky; and by night in a fiery splendour, not merely a lingering fiery splendour like that of the evening sky, but, as the words clearly indicate, a flaming brightness (lehâbâh ), and therefore real and living fire. The purpose of the cloud would not only be to overshadow, but also to serve as a wall of defence against opposing influences; (Note: The cloud derived its name, ‛ânân, not from the idea of covering, but from that of coming to meet one. The cloud…

In this chapter we have, I. A threatening of the paucity and scarceness of man (Isa 4:1), which might fitly enough have been added to the close of the foregoing chapter, to which it has a plain reference. II. A promise of the restoration of Jerusalem's peace and purity, righteousness and safety, in the days of the Messiah (Isa 4:2-6). Thus, in wrath, mercy is remembered, and gospel grace is a sovereign relief, in reference to the terrors of the law and the desolations made by sin.

4:5 The references to a canopy of cloud . . . and smoke and flaming fire recall God’s continuous presence and protection during the exodus from Egypt (Exod 13:21-22; 14:21-22).
