Joel 2:1-2, 12-17

Blow the trumpet in Zion;
sound the alarm on my holy mountain!
Let all the inhabitants of the land tremble,
for the day of the Lord is coming, it is near—
2 a day of darkness and gloom,
a day of clouds and thick darkness!
Like blackness spread upon the mountains
a great and powerful army comes;
their like has never been from of old,
nor will be again after them
in ages to come….
