Joel 2:12-13 New Revised Standard Version (NRSV)
12 Yet even now, says the Lord,
return to me with all your heart,
with fasting, with weeping, and with mourning;
13 rend your hearts and not your clothing.
Return to the Lord, your God,
for he is gracious and merciful,
slow to anger, and abounding in steadfast love,
and relents from punishing.
