Joel 2:4-8

The appearance of them is as the appearance of horses; and as horsemen, so shall they run.

Like the noise of chariots on the tops of mountains shall they leap, like the noise of a flame of fire that devoureth the stubble, as a strong people set in battle array.

Before their face the people shall be much pained: all faces shall gather blackness.

They shall run like mighty men; they shall climb the wall like men of war; and they shall march every one on his ways, and they shall not break their ranks:

Neither shall one thrust another; they shall walk every one in his path: and when they fall upon the sword, they shall not be wounded.
