Acts of the Apostles 2:16-21

No, what you see was predicted long ago by the prophet Joel: ‘In the last days,’ God says, ‘I will pour out my Spirit upon all people. Your sons and daughters will prophesy. Your young men will see visions, and your old men will dream dreams. In those days I will pour out my Spirit even on my servants—men and women alike— and they will prophesy. And I will cause wonders in the heavens above and signs on the earth below— blood and fire and clouds of smoke. The sun will become dark, and the moon will turn blood red before that great and glorious day of the LORD arrives. But everyone who calls on the name of the LORD will be saved.’
