Joel 2:8

He then adds, A man shall not push his brother. By this mode of speaking the Prophet means that they would come in perfect order, so that the multitude would create no confusion, as it is mostly the case: for it is very difficult for an army to march in regular order without tumult, like two or three men walking together. For when a hundred horsemen march together some commonly hinder others. When therefore so large a number assemble together, it can hardly be possible for them not to retard and impede one another. But the Prophet declares that this would not be the case with the Assyrians, for the Lord would direct their goings. Though then the Lord would bring so large a multitude, it would yet be so well arranged and in such order, that no one would push his companion, or be any hindrance to him. A man, he says, shall in his way proceed, even without any impediment.

And on swords they shall fall, and shall not be wounded: that is, they shall not only be strong men of war, so that they shall intrepidly face every kind of danger; but they shall also escape unhurt from all weapons; though they may rush on swords like madmen and show no care for themselves, they shall not yet be wounded. But this may be taken in a still simpler way, “They shall not be wounded” that is, as if they could not be wounded. And it seems to me to be the genuine sense of the Prophet, that they would not entertain any fear of death, so as cautiously to attack their enemies, but would with impunity provoke death itself by casting themselves on the very swords: they would not then fear any wound, but dare to face swords as if they were wholly harmless to them. Some render the word, “they shall not covet;” and then the word means as if the Prophet had said, that they would not be covetous of money. But this meaning can hardly suit this place; and we see that the best sense seems to be, that they would heedlessly rush on swords, as though they could not be wounded.
