Joel 2:10-12

New Catholic Bible

¹⁰ As they move forward,
    the earth quakes before them
    and the heavens tremble.
The sun and the moon are darkened,
    and the stars withhold their light.
¹¹ The Lord’s voice thunders
    at the head of his army.
Mighty and numerous are his forces,
    and they enforce his orders.
Great is the day of the Lord
    and exceedingly terrible;
    who can endure it?

¹² Yet even now, says the Lord,
    return to me with all your heart,
with fasting, with weeping, and with mourning.
