Joel 2:1-2
Blow the trumpet in Zion,
And sound an alarm in My holy mountain!
Let all the inhabitants of the land tremble;
For the day of the Lord is coming,
For it is at hand:
A day of darkness and gloominess,
A day of clouds and thick darkness,
Like the morning clouds spread over the mountains.
A people come, great and strong,
The like of whom has never been;
Nor will there ever be any such after them,
Even for many successive generations.
