Joel 2

2 For a day of dark and deep shade is near, a day of cloud and black night: like a black cloud a great and strong people is covering the mountains; there has never been any like them and will not be after them again, from generation to generation.

3 Before them fire sends destruction, and after them flame is burning: the land is like the garden of Eden before them, and after them an unpeopled waste; truly, nothing has been kept safe from them.
