(5) Declare.--i.e., proclaim as a herald proclaims. The cry is that of an alarm of war. The prophet sees, as it were, the invading army, and calls the people to leave their villages and to take refuge in the fortified cities.

Verses 5-31. - A revelation of grievous purport has suddenly reached the prophet. See how the foe draws nearer and nearer, and how alarm drives the scattered population to seek for refuge in the fortified cities. Can such be the issue of the promises of peace with which Jehovah has encouraged his people? Such are the contents of the first paragraph (vers. 5-10). Next,-in short, detached figures the prophet sets forth the sin of the people and its punishment. Like a scorching simoom is the former; like swift clouds, and like a whirlwind, is the onward march of the instruments of the latter. Swift, indeed, must repentance be, if it is to outrun punishment. For the northern peoples are already here (vers. 11-18). The impression is so strong on the mind of the prophet that he vents himself in language such as the last man might employ on the morrow of the final judgment day (vers. 19-26). And now, "lest what precedes might seem only poetry" (Payne Smith), the Divine decree is solemnly announced. The judgment is irrevocable; but there is a gleam of hope: "I will not make a full end." On the question whether the Scythians or the Baby-Ionians are mainly alluded to, see Introduction.) Verse 5. - Cry, gather together; rather, cry aloud.

4:5-18 The fierce conqueror of the neighbouring nations was to make Judah desolate. The prophet was afflicted to see the people lulled into security by false prophets. The approach of the enemy is described. Some attention was paid in Jerusalem to outward reformation; but it was necessary that their hearts should be washed, in the exercise of true repentance and faith, from the love and pollution of sin. When lesser calamities do not rouse sinners and reform nations, sentence will be given against them. The Lord's voice declares that misery is approaching, especially against wicked professors of the gospel; when it overtakes them, it will be plainly seen that the fruit of wickedness is bitter, and the end is fatal.Declare ye in Judah, and publish in Jerusalem, and say,.... Exhortations to repentance being without effect in general, though they might have an influence on some few particular persons, the Lord directs the prophet to lay before the people a view of their destruction as near at hand; who calls upon some persons as a sort of heralds, to publish and declare in the land of Judea, and in Jerusalem the metropolis of it, what follows:

blow ye the trumpet in the land; as an alarm of an approaching enemy, and of an invasion by him, and of danger from him; and this was to be done, not in order to gather together, and put themselves in a posture of defence, to meet the enemy, and give him battle; but to get together, that were in the fields, and in country villages, and hide themselves from him:

cry, gather together, and say; or cry with a full mouth, with a loud voice, that all might hear; which shows imminent danger:

assemble yourselves and let us go into the defenced cities; such as Jerusalem, and others, where they might think themselves safe and secure; see Matthew 24:16.
