Isaiah 5
26 Ref And he will let a flag be lifted up as a sign to a far-off nation, whistling to them from the ends of the earth: and they will come quickly and suddenly.
27 Ref There is no weariness among them, and no man is feeble-footed: they come without resting or sleeping, and the cord of their shoes is not broken.
28 Ref Their arrows are sharp, and every bow is bent: the feet of their horses are like rock, and their wheels are like a rushing storm.
29 Ref The sound of their armies will be like the voice of a lion, and their war-cry like the noise of young lions: with loud cries they will come down on their food and will take it away safely, and there will be no one to take it out of their hands.
