Joel 2:12-17

12"Yet even now," declares the Lord, "return to me with all your heart, with fasting, with weeping, and with mourning;

13and rend your hearts and not your garments." Return to the Lord your God, for he is gracious and merciful, slow to anger, and abounding in steadfast love; and he relents over disaster.

14Who knows whether he will not 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 solemn assembly;

16gather the people. Consecrate the congregation; assemble the elders; gather the children, even nursing infants. Let the bridegroom leave his room, and the bride her chamber.

17Between the vestibule and the altar let the priests, the ministers of the Lord, weep and say, "Spare your people, O Lord, and make not your heritage a reproach, a byword among the nations. Why should they say among the peoples, 'Where is their God?'"
