Isaiah 5:26-30

He will lift up a banner to signal the distant nations; he whistles for them to come from the ends of the earth. Look! Here they come, running swiftly and speedily! Not one warrior stumbles or grows weary— not even stopping to rest or sleep; they are battle ready! Their arrows are sharpened and every bow strung. Their horses’ hooves are hard as flint and their chariot wheels turn like the whirlwind. Their shout is like a lion’s roar, the roar of strong lions growling as they seize their prey. They carry away captives, and none can rescue them. They will roar and roar on that day like the roaring of crashing waves, and if you look back across the land you’ll see only darkness, disaster, and distress; daylight itself will be obscured by thick clouds.
