Joel 2:28-32

After this I will pour out my Spirit on everyone. Your sons and daughters will be my prophets, your old men will dream dreams, and your young men will see visions. In those days I will also pour out my Spirit on male slaves and female slaves. I will place wonders in the heavens and on earth: blood, and fire, and columns of smoke. The sun will turn dark, and the moon will turn red like blood at the coming of the great and fearful day of the Lord.” Then everyone who calls on the name of the Lord will be saved, rescued from Mount Zion and Jerusalem, as the Lord has said—these are among the survivors the Lord has called.
