(1) The burden of the valley of vision.—The “valley of vision” is Jerusalem, lying as it did (Jeremiah 21:13) in a valley, as compared with the hills round about it (Psalm 125:2). If we think of the prophet’s dwelling as being in the lower city, in the valley of Tyropœon, the epithet becomes still more appropriate. That valley would be to him in very deed a “valley of vision,” where he saw things present and to come. Possibly the name became more characteristic from the impulse given to the prophetic dreams of all who claimed to be seers. The prophet looks out, and sees the people in a state of excitement, caused probably by the near approach of the Assyrian armies. They are “on the house-tops,” the flat roofs of which were a customary place of concourse (Judges 16:27; Nehemiah 8:16), keeping their revels, as those do who meet the approach of danger with a reckless despair (Isaiah 22:13). By some commentators (Birks, Kay,) the “valley of vision” has been identified with Samaria.

(1) because there were several valleys "within" the city and adjacent to it, as the vale between mount Zion and Moriah; the vale between mount Moriah and mount Ophel; between these and mount Bezetha; and the valley of Jehoshaphat, without the walls of the city; or

(2) more probably it was called "a valley" in reference to its being "encompassed with hills," rising to a considerable elevation above the city.

Thus mount Olivet was on the east, and overlooked the city. Jerusalem is also called a "valley," and a "plain," in Jeremiah 21:13 : 'Behold, I am against thee, O inhabitant of the valley, and rock of the plain, saith the Lord.' Thus it is described in Reland's "Palestine:" - 'The city was in the mountain region of Judea, in an elevated place, yet so that in respect to the mountains by which it was surrounded, it seemed to be situated in a humble place, because mount Olivet, and other mountains surrounding it, were more elevated.' So Phocas says, 'The holy city is placed in the midst of various valleys and hills, and this is wonderful (Θαυμαστόν Thaumaston) in it, that at the same time the city seems to be elevated and depressed, for it is elevated in respect to the region of Judea, and depressed in respect to the hills around it.' (Reland's "Palestine," iii. 802, in Ugolini's "Thesaurus," vi.) It was common with Isaiah and the other prophets to designate Jerusalem and other places, not by their proper names, but by some appellation that would be descriptive (see Isaiah 21:1; Isaiah 29:1).

Of vision - (see the note at Isaiah 1:1). The word here means that Jerusalem was eminently the place where God made known his will to the prophets, and manifested himself to his people by "visions."

What aileth thee now? - What is the cause of the commotion and tumult that exists in the city? The prophets throws himself at once into the midst of the excitement; sees the agitation and tumult, and the preparations for defense which were made, and asks the "cause" of all this confusion.

That thou art wholly gone up to the house-tops - That all classes of the people had fled to the house-tops, so much that it might be said that all the city had gone up. Houses in the East were built in a uniform manner in ancient times, and are so to this day. (See a description of the mode of building in the notes at Matthew 9:1 ff.) The roofs were always flat, and were made either of earth that was trodden hard, or with large flat stones. This roof was surrounded with a balustrade Deuteronomy 22:8, and furnished a convenient place for walking, or even for eating and sleeping. Whenever, therefore, anything was to be seen in the street, or at a distance; or when there was any cause of alarm, they would naturally resort to the roof of the house. When there was a tower in the city, the inhabitants fled to that, and took refuge on its top (see Judges 9:50-53). The image here is, therefore, one of consternation and alarm, as if on the sudden approach of an enemy.

Isa 22:1-14. Prophecy as to an Attack on Jerusalem.

That by Sennacherib, in the fourteenth year of Hezekiah; Isa 22:8-11, the preparations for defense and securing of water exactly answer to those in 2Ch 32:4, 5, 30. "Shebna," too (Isa 22:15), was scribe at this time (Isa 36:3) [Maurer]. The language of Isa 22:12-14, as to the infidelity and consequent utter ruin of the Jews, seems rather to foreshadow the destruction by Nebuchadnezzar in Zedekiah's reign, and cannot be restricted to Hezekiah's time [Lowth].

1. of … valley of vision—rather, "respecting the valley of visions"; namely, Jerusalem, the seat of divine revelations and visions, "the nursery of prophets" [Jerome], (Isa 2:3; 29:1; Eze 23:4, Margin; Lu 13:33). It lay in a "valley" surrounded by hills higher than Zion and Moriah (Ps 125:2; Jer 21:13).

thee—the people of Jerusalem personified.

housetops—Panic-struck, they went up on the flat balustraded roofs to look forth and see whether the enemy was near, and partly to defend themselves from the roofs (Jud 9:51, &c.).The anguish of Judah: the prophet much grieved, Isaiah 22:1-5, by the Persians, Medes, and Assyrians, Isaiah 22:6,7. He reproveth their human wisdom, Isaiah 22:8-11, and profane joy, Isaiah 22:12,13; which God would certainly punish, Isaiah 22:14. Shebnah’s deprivation for his pride, Isaiah 22:15-19. Eliakim put in his place: his glory, Isaiah 22:20-25.

Of the valley of vision; of Judah; and especially of the City of Jerusalem, as the next verse showeth; which is called a valley, because a great part of it stood in a valley, and comparatively to those higher mountains wherewith it was encompassed; of which see Psalm 121:1 125:2 Isaiah 52:7; and the valley of vision, because of the many and clear visions or revelations of God’s mind in that place, above all other parts of the world. As the prophets are called seers, 1 Samuel 9:9, so prophecy is frequently called vision, as 1 Samuel 3:1 Isaiah 1:1 Ezekiel 7:13,26.

Gone up to the housetops, as they used to do in times of great confusion and consternation, that they might mourn, and look, and cry to Heaven for help. Compare Isaiah 15:3 Jeremiah 48:38.

"a prophecy concerning the inhabitants of the valley of Sion, to wit, the fields which are about Jerusalem.''

The Targum is,

"the burden of the prophecy concerning the city which dwells in the valley, of which the prophets prophesied;''

by all which it appears, that not the whole land of Judea is thought to be meant, only the city of Jerusalem, so called, not from its low estate into which it would fall, through the wickedness of the people, and so rather to be called a valley than a mountain, as Kimchi; but from its situation, it being, as Josephus (h) says, fortified with three walls, except on that side at which it was encircled with inaccessible valleys; and hence it may be, that one of its gates is called the valley gate, Nehemiah 2:13 and besides, there was a valley in it, between the mountains of Zion and Acra, which divided the upper and lower city, as he also elsewhere says (i). The burden of it is a heavy prophecy of calamities that should come upon it, or at least of a fright it should be put into, not in the times of Nebuchadnezzar, when it was taken and destroyed, as Jarchi and Kimchi, and another Jew Jerom makes mention of; nor in the times of Titus Vespasian, according to Eusebius, as the said Jerom relates; but in the times of Hezekiah, when Judea was invaded, and Jerusalem besieged by Sennacherib:

what aileth thee now? or, "what to thee now?" (k) what is come to thee? what is the matter with thee now? how comes this strange and sudden change?

that thou art wholly gone up to the housetops? not to burn incense to the queen of heaven, which was sometimes done, and is the sense of some mentioned by Aben Ezra; but either for safety, to secure themselves from their enemies; or to take a view of them, and observe their motions, and cast from thence their arrows and darts at them; or to look out for help, or to mourn over their distresses, and implore help of the Lord; see Isaiah 15:2 and this was the case, not only of some, but of them all; so that there was scarce a man to be seen in the streets, or in the lower parts of their houses, but were all gone up to the tops of them, which were built with flat roofs and battlements about them, Deuteronomy 22:8.
