Joel 2.12-13, 28-29
“Yet even now, says the Lord, return to me with all your heart, with fasting, with weeping, and with mourning; 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.
Then afterward I will pour out my spirit on all flesh; your sons and your daughters shall prophesy, your old men shall dream dreams, and your young men shall see visions. Even on the male and female slaves, in those days, I will pour out my spirit.”
