II. An express arrived with intelligence of the approach of the king of Babylon and his army. It is an evil that God will bring from the north (as he had said, ch. i. 15), even a great destruction, beyond all that had yet come upon the nation of the Jews. The enemy is here compared, 1. To a lion that comes up from his thicket, when he is hungry, to seek his prey, v. 7. The helpless beasts are so terrified with his roaring (as some report) that they cannot flee from him, and so become an easy prey to him. Nebuchadnezzar is this roaring tearing lion, the destroyer of the nations, that has laid many countries waste, and now is on his way in full speed towards the land of Judah. The destroyer of the Gentiles shall be the destroyer of the Jews too, when they have by their idolatry made themselves like the Gentiles. "He has gone forth from his place, from Babylon, or the place of the rendezvous of his army, on purpose against this land; that is the prey he has now his eye upon, not to plunder it only, but to make it desolate, and herein he shall succeed to such a degree that the cities shall be laid waste, without inhabitants, shall be overgrown with grass as a field;" so some read it. 2. To a drying blasting wind (v. 11), a parching scorching wind, which spoils the fruits of the earth and withers them, not a wind which brings rain, but such as comes out of the north, which drives away rain (Prov. xxv. 23), but brings something worse instead of it; such shall this evil out of the north be to this people, a black freezing wind, which they can neither fence against nor flee from, but, wherever they go, it shall surround and pursue them; and they cannot see it before it comes, but, when it comes, they shall feel it. It is a wind of the high places in the wilderness, or plain, that beats upon the tops of the hills or that carries all before it in the plain, where there is no shelter, but the ground is all champaign. It shall come in its full force towards the daughters of my people, that have been brought up so tenderly and delicately that they could not endure to have the wind blow upon them. Now this fierce wind shall come against them, not to fan, nor cleanse them, not such a gentle wind as is used in winnowing corn, but a full wind (v. 12), a strong and violent wind, blowing full upon them. This shall come to me, or rather for me; it shall come with commission from God and shall accomplish that for which he sends it; for this, as other stormy winds, fulfills his word. 3. To clouds and whirlwinds for swiftness, v. 13. The Chaldean army shall come up as clouds driven with the wind, so thick shall they stand, so fast shall they march, and it shall be to no purpose to offer to stop them or make head against them, any more than to arrest a cloud or give check to a whirlwind. The horses are swifter than eagles when they fly upon their prey; it is in vain to think either of opposing them or of outrunning them. 4. To watchers and the keepers of a field, v. 15-17. The voice declares from Dan, a city which lay furthest north of all the cities of Canaan, and therefore received the first tidings of this evil from the north and hastened it to Mount Ephraim, that part of the land of Israel which lay next to Judea; they received the news of the affliction and transmitted it to Jerusalem. Ill news flies apace; and an impenitent people, that hates to be reformed, can expect no other that ill news. Now, what is the news? "Tell the nations, those mixed nations that now inhabit the cities of the ten tribes, mention it to them, that they may provide for their own safety; but publish it against Jerusalem, that is the place aimed at, the game shot at, let them know that watchers have come from a far country, that is, soldiers, that will watch all opportunities to do mischief." Private soldiers we call private sentinels, or watchmen. "They are coming in full career, and give out their voice against the cities of Judah; they design to invest them, to make themselves masters of them, and to attack them with loud shouts, as sure of victory. As keepers of a field surround it, to keep all out from it, so shall they surround the cities of Judah, to keep all in them, till they be constrained to surrender at discretion; they are against her round about, compassing her in on every side." See Luke xix. 43. As formerly the good angels, those watchers, and holy ones, were like keepers of a field to Jerusalem, watching about it, that nothing might go in to its prejudice, so now their enemies were as watchers and keepers of a field, surrounding it that nothing might go in to its relief and succour.
