By saying that they would come to the prey, he means that they would have no trouble or labor, for they would be victorious before they had any contest, or had any war with their enemies. The meaning then is, that the Chaldeans would not come to spend much time in warfare, as when there is a strong power to resist; but that they would only come for the booty, for the Jews would be frightened, and instantly submit themselves. And by these words the Prophet intimates, that there would be neither strength nor courage in a people so refractory: for God thus debilitates the hearts of those who fiercely resist his word. Whenever, then, men become strong against God, he so melts their hearts, that they cannot resist their fellow-mortals; and thus he mocks their confidence, or rather their madness. Lest then the Jews should still harbor any hope from the chance of war, the Prophet says that the Chaldeans would only come for the prey, for all would become subject to them. He afterwards adds, that the meeting of their faces would be like the oriental wind. The word gmh, gime, means what is opposite; and its derivative signifies meeting or opposition (occursus.) We indeed know that the east wind was very injurious to the land of Judea, that it dried up vegetation, yea, that it consumed as it were the whole produce of the earth. The violence of that wind was also very great. Hence whenever the Prophets wished to express a violent impetuosity, they added this comparison of the east wind. It was therefore the same as though the Prophet had said that the Jews would now in vain flatter themselves; for as soon as they perceived the blowing of the east wind, they would flee away, knowing that they would be wholly unable to stand against it. [1] Hence follows what is added by the Prophets, He shall gather the captivity like the sand; that is, the king of Babylon shall without any trouble subdue all the people, and collect captives innumerable as the sand; for by the sand of the sea is meant an immense number of men. In short, the Prophet shows that the Jews were already conquered; because their striving and their contest had been with God, whom they had so often and so obstinately provoked; and also, because God had chosen for himself such servants as excelled in quickness, and power, and cruelty. This is the sum of the whole. He afterwards adds--

1 - This clause has been variously interpreted. The Targum, Vulgate, and Symmachus, countenance the view given here. There is no help from the Septuagint, as no sense is given. The word [mgmch], only found here, is rendered by Symmachus, prosopsis, sight, aspect. Targum explains it by a word which signifies "front." Henderson and Lee regard this as its meaning. Others, as Newcome and Drusius render it, supping up, or absorption, and derive it from [gm'], to drink up, to absorb; and they regard the idea to be, that the very presence of the Chaldeans would absorb every thing like a scorching wind. But "the supping up of their faces shall be as the east wind," which is Newcome's version, is an odd phrase. The last word has [h] affixed to it, which is never the case when it means the east wind. It is by all admitted, that "towards the east" is its proper construction. Hence the most probable rendering of this passage is, "The aspect of their faces shall be towards the east;" and with this corresponds what follows, that they should "gather captives as the sand;" that is, that they might carry them away to the place where they turned their faces. The version of Henderson, which is essentially that of Symmachus, is the following,-- The aspect of their faces is like the east wind. He owns the difficulty as to the last word, and views it here as in an irregular form. Dathius gives this paraphrase,-- It will have its face direct towards the east. He says that the word [qdvm], by itself never means the pestilential wind from the east; but that when it means this, it has another word attached to it.--Ed.

They shall come all for violence - "Violence" had been the sin of Judah Habakkuk 1:3-4, and now violence shall be her punishment. It had been ever before the prophet; all were full of it. Now should violence be the very end, one by one, of all the savage horde poured out upon them; they all, each one of them come for violence.
Their faces shall sup up as the east wind - קדומה occurs else only in Ezekiel 11:1, and Ezekiel 11:16 times in Ezek. 40-48 of the ideal city and temple as "Eastwards." But except in the far-fetched explanation of Abarb (mentioned also by Tanchum) that they ravaged, not to settle but to return home with their booty, "Eastwards" would have no meaning. Yet "forwards" is just as insulated a rendering as that adopted by John and D. Kimchi, A. E. Rashi, Oh. Sip., Sal. B. Mel. Arab Tr. (following Jonathan) "the East-wind; קדומה standing as a metaphor instead of a simile the הbeing regarded as paragogic, as in לילה. So also Symmachus ἄνεμος καύσων anemos kausōn. Jerome: "ventus urens.") "As at the breath of the burning wind all green things dry up, so at sight of these all shall be wasted." They shall sweep over everything impetuously, like the east wind, scorching, blackening, blasting, swallowing up all, as they pass over, as the East wind, especially in the Holy Land, sucks up all moisture and freshness.
And they shall gather the captivity - i. e., the captives
As the sand - countless, as the particles which the East wind raises, sweeping over the sand-wastes, where it buries whole caravans in one death.

Their faces shall sup up as the east wind - This may be an allusion to those electrical winds which prevail in that country. Mr. Jackson, in his overland journey from India, mentions his having bathed in the Tigris. On his coming out of the river one of those winds passed over him, and, in a moment, carried off every particle of water that was on his body and in his bathing dress. So, the Chaldeans shall leave no substance behind them; their faces, their bare appearance, is the proof that nothing good shall be left.
Shall gather the captivity as the sand - They shall carry off innumerable captives.

They shall come all for violence: their faces shall sup up [as] the (f) east wind, and they shall gather the captives (g) as the sand.
(f) For the Jews most feared this wind, because it destroyed their fruits.
(g) They will be so many in number.

They shall come all for violence,.... Or, "the whole of it" (s); the whole army of the Chaldeans, everyone of them; this would be their sole view, not to do themselves justice, as might be pretended, or avenge any injuries or affronts done to them by the Jews; but purely for the sake of spoil and plunder:
their faces shall sup up as the east wind: their countenances will appear so stern and fierce, that their very looks will so frighten, as to cause men to sink and die through terror; just as herbs and plants shrivel up and wither away, when blasted by a nipping east wind. So the Targum,
"the reception or look of their faces is like to a vehement east wind.''
Some render it,
"the look or design of their faces is to the east (t);''
when the Chaldeans were on their march to Judea, their faces were to the west or south west; but then their desire and views were, that when they had got the spoil they came for, as in the preceding clause, to carry it to Babylon, which lay eastward or north east of Judea, and thither their faces looked:
and they shall gather the captivity as the sand; or gather up persons, both in Judea, and in other countries conquered by them, as innumerable as the sand of the sea, and carry them captive into their own land. Captivity is put for captives.

all for violence--The sole object of all is not to establish just rights, but to get all they can by violence.
their faces shall sup up as the east wind--that is, they shall, as it were, swallow up all before them; so the horse in Job 39:24 is said to "swallow the ground with fierceness and rage." MAURER takes it from an Arabic root, "the desire of their faces," that is, the eager desire expressed by their faces. HENDERSON, with SYMMACHUS and Syriac, translates, "the aspect."
as the east wind--the simoon, which spreads devastation wherever it passes (Isaiah 27:8). GESENIUS translates, "(is) forwards." The rendering proposed, eastward, as if it referred to the Chaldeans' return home eastward from Judea, laden with spoils, is improbable. Their "gathering the sand" accords with the simoon being meant, as it carries with it whirlwinds of sand collected in the desert.

For violence - To enrich themselves by making a prey of all. Their faces - Their very countenances shall be as blasting as the east - wind.
