Joel 2:11-13

American Standard Version

¹¹ And Jehovah uttereth his voice before his army; for his camp is very great; for he is strong that executeth his word; for the day of Jehovah is great and very terrible; and who can abide it?

¹² Yet even now, saith Jehovah, turn ye unto me with all your heart, and with fasting, and with weeping, and with mourning: ¹³ and rend your heart, and not your garments, and turn unto Jehovah your God; for he is gracious and merciful, slow to anger, and abundant in lovingkindness, and repenteth him of the evil.
