Joel 2:1-2

New Century Version

2 Blow the trumpet in Jerusalem;
    shout a warning on my holy mountain.
Let all the people who live in the land shake with fear,
    because the Lord’s day of judging is coming;
    it is near.
² It will be a dark, gloomy day,
    cloudy and black.
Like the light at sunrise,
    a great and powerful army will spread over the mountains.
There has never been anything like it before,
    and there will never be anything like it again.
