Joel 2:28-32

2:28 “It will happen afterward, that I will pour out my Spirit on all flesh; and your sons and your daughters will prophesy. Your old men will dream dreams. Your young men will see visions.

2:29 And also on the servants and on the handmaids in those days, I will pour out my Spirit.

2:30 I will show wonders in the heavens and in the earth: blood, fire, and pillars of smoke.

2:31 The sun will be turned into darkness, and the moon into blood, before the great and terrible day of the LORD comes.

2:32 It will happen that whoever will call on the LORD’s name shall be saved; for in Mount Zion and in Jerusalem there will be those who escape, as the LORD has said, and amongst the remnant, those whom the LORD calls.
