Acts 2:16-21 (KJV)
16 But this is that which was spoken by the prophet Joel;
17 And it shall come to pass in the last days, saith God, I will pour out of my Spirit upon all flesh: and your sons and your daughters shall prophesy, and your young men shall see visions, and your old men shall dream dreams:
18 And on my servants and on my handmaidens I will pour out in those days of my Spirit; and they shall prophesy:
19 And I will shew wonders in heaven above, and signs in the earth beneath; blood, and fire, and vapour of smoke:
20 The sun shall be turned into darkness, and the moon into blood, before the great and notable day of the Lord come:
21 And it shall come to pass, that whosoever shall call on the name of the Lord shall be saved.
