Isaiah 5:25-30

25So the Lord is furious with his people; he lifts his hand and strikes them. The mountains shake, and corpses lie like manure in the middle of the streets. Despite all this, his anger does not subside, and his hand is ready to strike again.

26He lifts a signal flag for a distant nation, he whistles for it to come from the far regions of the earth. Look, they come quickly and swiftly.

27None tire or stumble, they don’t stop to nap or sleep. They don’t loosen their belts, or unstrap their sandals to rest.

28Their arrows are sharpened, and all their bows are prepared. The hooves of their horses are hard as flint, and their chariot wheels are like a windstorm.

29Their roar is like a lion’s; they roar like young lions. They growl and seize their prey; they drag it away and no one can come to the rescue.

30At that time they will growl over their prey, it will sound like sea waves crashing against rocks. One will look out over the land and see the darkness of disaster, clouds will turn the light into darkness.
