Joel 2:9-12

9They run to and fro in the city, They run on the wall; They climb into the houses, They enter at the windows like a thief.

10The earth quakes before them, The heavens tremble; The sun and moon grow dark, And the stars diminish their brightness.

11The Lord gives voice before His army, For His camp is very great; For strong is the One who executes His word. For the day of the Lord is great and very terrible; Who can endure it?

12“Now, therefore,” says the Lord, “Turn to Me with all your heart, With fasting, with weeping, and with mourning.”
