15 For these men are not inebriated, as you suppose, for it is the third hour of the day.
16 But this is what was spoken of by the prophet Joel:
17 'And this shall be: in the last days, says the Lord, I will pour out, from my Spirit, upon all flesh. And your sons and your daughters shall prophesy. And your youths shall see visions, and your elders shall dream dreams.
18 And certainly, upon my men and women servants in those days, I will pour out from my Spirit, and they shall prophesy.
19 And I will bestow wonders in heaven above, and signs on earth below: blood and fire and the vapor of smoke.
20 The sun shall be turned into darkness and the moon into blood, before the great and manifest day of the Lord arrives.
21 And this shall be: whoever shall invoke the name of the Lord will be saved.'
