Joel 2:12-14

12Yet even now, saith Jehovah, turn to me with all your heart, and with fasting, and with weeping, and with mourning;

13and rend your heart, and not your garments, and turn unto Jehovah your 1God: for he is gracious and merciful, slow to anger, and of great loving-kindness, and repenteth him of the evil.

14Who knoweth? He might return and repent, and leave a blessing behind him, an oblation and a drink-offering for Jehovah your 2God?
