(5) For it is a day of trouble.--The earlier clauses paint the mental emotions of the coming day of judgment. In the latter we hear the actual crash of the battering-rams across the walls. The cry of the panic-stricken people shall rise to the surrounding mountains, possibly as to the hills from whence they expected help, either as true worshippers looking to Mount Zion (Psalm 121:1), or to the high places which were so long the objects of their worship, and which led their enemies to say that their gods were "gods of the hills, and not of the valleys" (1Kings 20:23).

Verse 5. - It is a day... By the Lord; rather, there is a day to the Lord; or, the Lord has a day. God has in reserve such a day; and it will assuredly arrive in due course. Hence the prophet's grief. In the valley of vision. We may suppose that Hezekiah, before he made the submission recorded in 2 Kings 18:14 and in the 'Cylinder of Sennacherib,' col. 4:11. 28, 29, tried the chances of battle against the Assyrians in this valley, and that Isaiah had a prophetic vision of the fight. Breaking down the walls; rather, undermining. The Assyrian sculptures show numerous examples of this practice. Sometimes swords or spears are used to dislodge the stones of the wall, sometimes crow-bars or axes (see 'Ancient Monarchies,' vol. 2. p. 82). Crying. Some regard this word, and also that translated "the walls" in the preceding clause, as proper names, and render the passage, "Kir undermineth, and Shoa is at the mount" (Ewald, Cheyne, Luzzatto). But it seems unlikely that "Kit" would be mentioned twice.

22:1-7 Why is Jerusalem in such terror? Her slain men are not slain with the sword, but with famine; or, slain with fear, disheartened. Their rulers fled, but were overtaken. The servants of God, who foresee and warn sinners of coming miseries, are affected by the prospect. But all the horrors of a city taken by storm, faintly shadow forth the terrors of the day of wrath.For it is a day of trouble,.... To Hezekiah, and also Jerusalem, and all the inhabitants of the land:

and of treading down; the people of it by Sennacherib's army, like mire in the streets, when their cities were taken by him:

and of perplexity by the Lord of hosts in the valley of vision; in Jerusalem, besieged, and threatened with desolation; which threw the king and his nobles, and all the inhabitants, into the utmost perplexity, confusion, and distress; and all this was not merely from men, nor was it by chance, but by the permission and appointment of God, to humble his people for their sins, and bring them to a sense and acknowledgment of them:

breaking down the walls: of the fenced cities, with their battering rams, at the time they besieged and took them, 2 Kings 18:13,

and of crying to the mountains: looking and running to them for help and succour, for shelter and protection; and crying so loud, by reason of their distress, as that it reached the distant mountains, and made them echo with it.
