Joel 2:9-12

9They storm the city; they run on the wall; they climb into the houses; they enter through the windows like thieves.

10The earth quakes before them; the sky shakes. The sun and moon grow dark, and the stars cease their shining.

11The Lord makes his voice heard in the presence of his army. His camp is very large; those who carry out his command are powerful. Indeed, the day of the Lord is terrible and dreadful  — who can endure it?

12Even now — this is the Lord’s declaration — turn to me with all your heart, with fasting, weeping, and mourning.
