Isaiah 5:26-28

26And he will lift up a banner to the nations afar off, and will hiss for one from the end of the earth; and behold, it will come rapidly [and] lightly.

27None among them is weary, none stumbleth; they slumber not, nor sleep; none hath the girdle of his loins loosed, nor the thong of his sandals broken;

28their arrows are sharp, and all their bows bent; their horses' hoofs are reckoned as the flint, and their wheels as a whirlwind.
