a day of darkness and gloom, a day of clouds and blackness. Like the dawn overspreading the mountains a great and strong army appears, such as never was of old, nor will ever be in ages to come.
KJV
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.
ASV
