Joel 2:10-12 New International Version - UK (NIVUK)
10 Before them the earth shakes,
the heavens tremble,
the sun and moon are darkened,
and the stars no longer shine.
11 The Lord thunders
at the head of his army;
his forces are beyond number,
and mighty is the army that obeys his command.
The day of the Lord is great;
it is dreadful.
Who can endure it?
Rend your heart
12 ‘Even now,’ declares the Lord,
‘return to me with all your heart,
with fasting and weeping and mourning.’
