Joel 2:5-8 New International Version (NIV)

5. With a noise like that of chariots they leap over the mountaintops, like a crackling fire consuming stubble, like a mighty army drawn up for battle.

6. At the sight of them, nations are in anguish; every face turns pale.

7. They charge like warriors; they scale walls like soldiers. They all march in line, not swerving from their course.

8. They do not jostle each other; each marches straight ahead. They plunge through defenses without breaking ranks.
