Acts 2:16-21
16 This is what the prophet Joel announced would happen: 17 "In the Last Days," God says, "I will pour out my Spirit on every kind of people: Your sons will prophesy, also your daughters; Your young men will see visions, your old men dream dreams. 18 When the time comes, I'll pour out my Spirit On those who serve me, men and women both, and they'll prophesy. 19 I'll set wonders in the sky above and signs on the earth below, Blood and fire and billowing smoke, 20 the sun turning black and the moon blood-red, Before the Day of the Lord arrives, the Day tremendous and marvelous; 21 And whoever calls out for help to me, God, will be saved."

Joel is in the Old Testament.
