Acts 2:18-21

Yea and on my servants and on my handmaidens in those days Will I pour forth of my Spirit; and they shall prophesy. And I will show wonders in the heaven above, And signs on the earth beneath; Blood, and fire, and vapor of smoke: The sun shall be turned into darkness, And the moon into blood, Before the day of the Lord come, That great and notable day: And it shall be, that whosoever shall call on the name of the Lord shall be saved.
