Isaiah 5:26-29

26He lifts a banner for the distant nations and whistles for those at the ends of the earth. Behold—how speedily and swiftly they come!27None of them grows weary or stumbles; no one slumbers or sleeps. No belt is loose and no sandal strap is broken.28Their arrows are sharpened, and all their bows are strung. The hooves of their horses are like flint; their chariot wheels are like a whirlwind.29Their roaring is like that of a lion; they roar like young lions. They growl and seize their prey; they carry it away, and no one can rescue it.
