Joel 2:1-17 Joel sees a plague of locusts as a sign of the coming of the ‘Day of the LORD’. He calls on the people to repent with fasting and mourning:
"Blow the trumpet in Jerusalem; shout a warning on my holy mountain. Let all the people who live in the land shake with fear, because the LORD's day of judging is coming; it is near." (Joel 2:1)

"The LORD says, 'Even now, come back to me with all your heart. Go without food, and cry and be sad...' Come back to the LORD your God, because he is kind and shows mercy." (Joel 2:12-13)
Joel 2:18-32 The LORD promises to restore the land before the ‘Day of the LORD’ arrives:
“After this, I will pour out my Spirit on all kinds of people. Your sons and your daughters will prophesy, your old men will dream dreams, and your young men will see visions. At that time I will pour out my Spirit also on male slaves and female slaves. I will show miracles in the sky and on the earth... The sun will become dark, the moon red as blood, before the overwhelming and terrible day of the LORD comes.Then anyone who calls on the LORD will be saved.” (Joel 2:28-32)
