Joel 2:11-15

11The 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?

12“Even now,” declares the Lord, “return to me with all your heart, with fasting and weeping and mourning.”

13Rend your heart and not your garments. Return to the Lord your God, for he is gracious and compassionate, slow to anger and abounding in love, and he relents from sending calamity.

14Who knows? He may turn and relent and leave behind a blessing— grain offerings and drink offerings for the Lord your God.

15Blow the trumpet in Zion, declare a holy fast, call a sacred assembly.
