Joel 2:4

1 Blow ye the trumpet in Zion, and sound an alarm in my holy mountain: let all the inhabitants of the land tremble: for the day of the LORD cometh, for [it is] nigh at hand;

2 A day of darkness and of gloominess, a day of clouds and of thick darkness, as the morning spread upon the mountains: a great people and a strong; there hath not been ever the like, neither shall be any more after it, [even] to the years of many generations.

3 A fire devoureth before them; and behind them a flame burneth: the land [is] as the garden of Eden before them, and behind them a desolate wilderness; and nothing shall escape them.

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.

7 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:
