Isaiah 4:6

Thus would Zion be a secure retreat from all adversities and disasters."And it will be a booth for shade by day from the heat of the sun, and for a refuge and covert from storm and from rain." The subject to "will be" is not the miraculous roofing; for ânân (cloud) is masculine, and the verb feminine, and there would be no sense in saying that a Chuppâh or canopy would be a succâh or booth. Either, therefore, the verb contains the subject in itself, and the meaning is, "There will be a booth" (the verb hâyâh being used in a pregnant sense, as in Isa 15:6; Isa 23:13); or else Zion (Isa 4:5) is the subject. We prefer the latter. Zion or Jerusalem would be a booth, that is to say, as the parallel clause affirms, a place of security and concealment (mistor, which only occurs here, is used on account of the alliteration with machseh in the place of sether, which the prophet more usually employs, viz., in Isa 28:17; Isa 32:2). "By day" (yōmâm, which is construed with לצל in the construct state, cf., Eze 30:16) is left intentionally without any "by night" to answer to it in the parallel clause, because reference is made to a place of safety and concealment for all times, whether by day or night. Heat, storm, and rain are mentioned as examples to denote the most manifold dangers; but it is a singular fact that rain, which is a blessing so earnestly desired in the time of Chōreb, i.e., of drought and burning heat, should also be included. At the present day, when rain falls in Jerusalem, the whole city dances with delight. Nevertheless rain, i.e., the rain which falls from the clouds, is not paradisaical; and its effects are by no means unfrequently destructive. According to the archives of Genesis, rain from the clouds took the place of dew for the first time at the fl…

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.

4:6 shelter (literally shadow; see 32:2): See 32:2; God’s protection would keep the remnant safe from enemies and from the destruction he would bring on the wicked (33:14-16).
