17 And it shall be in the last days, saith God, I will pour forth 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 Yea and on my servants and on my handmaidens in those days Will I pour forth of my Spirit; and they shall prophesy. 19 And I will shew wonders in the heaven above, And signs on 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 day of the Lord come, That great and notable day: 21 And it shall be, that whosoever shall call on the name of the Lord shall be saved.
