Joel 2:1-2

Young's Literal Translation

2 Blow ye a trumpet in Zion, And shout ye in My holy hill, Tremble do all inhabitants of the earth, For coming is the day of Jehovah, for [it is] near!

² A day of darkness and thick darkness, A day of cloud and thick darkness, As darkness spread on the mountains, A people numerous and mighty, Like it there hath not been from of old, And after it there is not again -- till the years of generation and generation.
