Joel 2:4-6

King James Version

⁴ The appearance of them is as the appearance of horses; and as horsemen, so shall they run.

⁵ 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.

⁶ Before their face the people shall be much pained: all faces shall gather blackness.
