Joel 2:11-15

11The Lord gives voice before His army, For His camp is very great; For strong is the One who executes His word. For the day of the Lord is great and very terrible; Who can endure it?

12“Now, therefore,” says the Lord, “Turn to Me with all your heart, With fasting, with weeping, and with mourning.”

13So rend your heart, and not your garments; Return to the Lord your God, For He is gracious and merciful, Slow to anger, and of great kindness; And He relents from doing harm.

14Who knows if He will turn and relent, And leave a blessing behind Him— A grain offering and a drink offering For the Lord your God?

15Blow the trumpet in Zion, Consecrate a fast, Call a sacred assembly;
