And he will lift up an ensign to the nations from far, and will hiss unto them from the end of the earth: and, behold, they shall come with speed swiftly: None shall be weary nor stumble among them; none shall slumber nor sleep; neither shall the girdle of their loins be loosed, nor the latchet of their shoes be broken: Whose arrows are sharp, and all their bows bent, their horses’ hoofs shall be counted like flint, and their wheels like a whirlwind: Their roaring shall be like a lion, they shall roar like young lions: yea, they shall roar, and lay hold of the prey, and shall carry it away safe, and none shall deliver it. And in that day they shall roar against them like the roaring of the sea: and if one look unto the land, behold darkness and sorrow, and the light is darkened in the heavens thereof.
God will cause the Babylonians to come to Jerusalem. The Jews would see their troops approaching, in top physical condition, perfectly uniformed, and well armed. The horses and chariots would approach fast and furiously. The troops would pounce like a lion upon the populace, and then carry the people off into exile. It would be a dark day for Judah.
