Joel 2:1-3

21st Century King James Version

2 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; yea, and nothing shall escape them.
