“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;
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.
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; yea, and nothing shall escape them.
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.
They shall run to and fro in the city; they shall run upon the wall, they shall climb up upon the houses; they shall enter in at the windows like a thief.
The earth shall quake before them; the heavens shall tremble: the sun and the moon shall be dark, and the stars shall withdraw their shining:
And the LORD shall utter his voice before his army: for his camp [is] very great: for [he is] strong that executeth his word: for the day of the LORD [is] great and very terrible; and who can abide it?
Therefore also now, saith the LORD, turn ye [even] to me with all your heart, and with fasting, and with weeping, and with mourning:
And rend your heart, and not your garments, and turn unto the LORD your God: for he [is] gracious and merciful, slow to anger, and of great kindness, and repenteth him of the evil.” Joel 2:1-13 (KJV)
