Joel 2:1-2

New Living Translation

2 Sound the trumpet in Jerusalem^[a]!
    Raise the alarm on my holy mountain!
Let everyone tremble in fear
    because the day of the Lord is upon us.
² It is a day of darkness and gloom,
    a day of thick clouds and deep blackness.
Suddenly, like dawn spreading across the mountains,
    a great and mighty army appears.
Nothing like it has been seen before
    or will ever be seen again.
