And a covering in the day-time shall be a shadow from the heat. Though the Prophet confirms what we have already noticed, that God will be our perpetual guide till he has brought us to the end of our journey, yet we are reminded that believers will always be exposed to numerous calamities. Scorching heat, and piercing cold, and still heavier distresses, press on them severely; when they escape from one danger, they meet with another. But the highest consolation is that against every inconvenience the shadow of the Lord will of itself be sufficient; for it will cover them in such a manner that nothing can injure or do them any harm. Although, therefore, various calamities and afflictions surround us on every side, still the Lord promises that he will assist us; as it is said in the Psalm, The sun shall not scorch thee by day, nor the moon by night; for the Lord will preserve thee from all evil. (Psalm 121:6, 7.) Nothing more is necessary than that we follow our calling, and perform our duty faithfully. It belongs equally to the condition of the good and of the bad that they suffer many inconveniencies; but bad men have no refuge, no place of concealment in which they may hide themselves, and they must be utterly overwhelmed. But blessed is the condition of the godly; for although they endure heat and cold, still they have a safe refuge in God. But that glory of which we formerly spoke must shine in us; otherwise we shall have no share in these things; and if we carry about with us God's mark, whenever we shall be assailed by a tempest, let us rest assured that he will be our protection.

And there shall be a tabernacle - The reference here is to the "tabernacle," or sacred "tent" that God directed Moses to make in the wilderness. The image of the cloudy pillar mentioned in the previous verses, seems to have suggested to the mind of the prophet the idea of the tabernacle over which that pillar rested. The principal idea here is, however, not a tabernacle as a symbol of the divine protection, or of divine worship, but of a place of refuge from a tempest; that is, that they should be "safe" under his protection. In Eastern countries they dwelt chiefly in tents. The idea is, therefore, that God would furnish them a place of shelter, a hiding-place from the storm.
In the daytime from the heat - The heat in those regions was often very intense, particularly in the vast plains of sand. The "idea" here is, therefore, one that is very striking. It means, that God would furnish to them a refuge that would be like the comfort derived from a tent in a burning desert.
For a place of refuge - A place to which to flee in the midst of a storm, as a tent would be.
A covert - A place of retreat, a safe place to retire to. The figure used here is not unfrequently employed in the prophets; Isaiah 25:4; Isaiah 32:2. In eastern countries this idea would be very striking. While traversing the burning sands of a desert, exposed to the rays of a tropical sun, nothing could be more grateful than the cool shadow of a rock. Such figures are, therefore, common in oriental writings, to denote protection and agreeable shelter from calamities; see the note at Isaiah 32:2. The idea in these verses is:
(1) That God will be a defender of his people.
(2) That he will protect their families, and that his blessing will be upon their dwelling-places; compare the note at Isaiah 59:21.
(3) They may expect his blessing on their religious assemblies.
(4) God, through the promised Messiah, would be a refuge and defense.
The sinner is exposed to the burning wrath of God, and to the storms of divine vengeance that shall beat forever on the naked soul in hell. From all this burning wrath, and from this raging tempest, the Messiah is the only refuge. Through him God forgives sin; and united to him by faith, the soul is safe. There are few images more beautiful than this. Soon the storms of divine vengeance will beat on the sinner. God will summon him to judgment. But then, he who has fled to the Messiah - the Lord Jesus - as the refuge of his soul, shall be safe. He shall have nothing to fear, and in his arms shall find defense and salvation.

A tabernacle - In countries subject to violent tempests, as well as to intolerable heat, a portable tent is a necessary part of a traveller's baggage, for defense and shelter. And to such tents the words of the text make evident allusion. They are to be met with in every part of Arabia and Egypt, and in various other places in the East.

And there shall be a tabernacle for a shade in the daytime from the heat, and for a place of refuge, and for a covert from storm (k) and from rain.
(k) God promises to be the defence of his Church against all troubles and dangers.

And there shall be a tabernacle,.... Christ, who tabernacled in our nature, and is the minister of the true tabernacle, which God pitched, and not man; who will be spiritually present in the word and ordinances, where the shepherds pitch their tents; and who will be that to his people as shepherds' tents are to them, to which the allusion is:
for a shadow in the day time from the heat: from the heat of a fiery law, which works wrath; from the flaming sword of justice, which calls for vengeance; from the wrath of God, which is poured forth like fire; from Satan's temptations, compared to fiery darts; and from the violence of persecution; for there will be no more after the last struggle of the beast, and the slaying of the witnesses:
and for a place of refuge; until the indignation be over and past: as Christ is a refuge for sensible sinners to flee unto for safety, from avenging justice, and the wrath of God; so he is a place of security, and has his chambers of safety for saints, from all dangers, and from every enemy, Isaiah 26:20,
and for a covert from storm and from rain; from the blast of the terrible ones, the antichristian powers, which will be as a storm against a wall, Isaiah 25:4 this will be the hour of temptation, which will come upon and try them that dwell upon the earth, from which Christ will preserve his faithful ones, Revelation 3:10.

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 Isaiah 15:6; Isaiah 23:13); or else Zion (Isaiah 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 Isaiah 28:17; Isaiah 32:2). "By day" (yōmâm, which is construed with לצל in the construct state, cf., Ezekiel 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 flood, when it fell in a continuous and destructive form. The Jerusalem of the last time will be paradise restored; and there men will be no longer exposed to destructive changes of weather. In this prediction the close of the prophetic discourse is linked on to the commencement. This mountain of Zion, roofed over with a cloud of smoke by day and the shining of a flaming fire by night, is no other than the mountain of the house of Jehovah, which was to be exalted above all the mountains, and to which the nations would make their pilgrimage; and this Jerusalem, so holy within, and all glorious without, is no other than the place from which the word of Jehovah was one day to go forth into all the world. But what Jerusalem is this? Is it the Jerusalem of the time of final glory awaiting the people of God in this life, as described in Revelation 11 (for, notwithstanding all that a spiritualistic and rationalistic anti-chiliasm may say, the prophetic words of both Old and New Testament warrant us in expecting such a time of glory in this life); or is it the Jerusalem of the new heaven and new earth described in Revelation 20:1-15 :21? The true answer is, "Both in one." The prophet's real intention was to depict the holy city in its final and imperishable state after the last judgment. But to his view, the state beyond and the closing state here were blended together, so that the glorified Jerusalem of earth and the glorified Jerusalem of heaven appeared as if fused into one. It was a distinguishing characteristic of the Old Testament, to represent the closing scene on this side the grave, and the eternal state beyond, as a continuous line, having its commencement here. The New Testament first drew the cross line which divides time from eternity. It is true, indeed, as the closing chapters of the Apocalypse show, that even the New Testament prophecies continue to some extent to depict the state beyond in figures drawn from the present world; with this difference, however, that when the line had once been drawn, the demand was made, of which there was no consciousness in the Old Testament, that the figures taken from this life should be understood as relating to the life beyond, and that eternal realities should be separated from their temporal forms.

And there - Or, he, the Lord, shall be a tabernacle, to defend them from the heat of the sun, and other injuries of the weather.
