Joel 2:28-31

“After this, I will pour out my Spirit on all kinds of people. Your sons and daughters will prophesy, your old men will dream dreams, and your young men will see visions. At that time I will pour out my Spirit also on male slaves and female slaves. I will show miracles in the sky and on the earth: blood, fire, and thick smoke. The sun will become dark, the moon red as blood, before the overwhelming and terrible day of the LORD comes.
