When did you start caring what the Bible says?<quoted text>
Where does it say that?
ACTS 2:18-20 ("And on my servants and on my handmaidens I will pour out in those days of my Spirit; and they shall prophesy: And I will shew wonders in heaven above, and signs in the earth beneath; blood, and fire, and vapour of smoke: The sun shall be turned into darkness, and the moon into blood, before that great and notable day of the Lord come") versus JOEL 2:29-31 ("And also upon the servants and upon the handmaids in those days will I pour out my spirit. And I will shew wonders in the heavens and in the earth, blood and fire, and pillars of smoke. The sun shall be turned into darkness, and the moon into blood, before the great and the terrible day of the Lord come"). Peter misquoted Joel in several respects.
(a) Joel says "the" servants and "the" handmaids rather than "my" servants and "my" handmaids and says nothing about them prophesying.
(b) Joel says "the heavens," which is plural, rather than "heaven above."
(c) Joel does not have "beneath" or "signs," and he has "pillars" instead of "vapour."
(d) And Joel has "terrible day" rather than "notable day" which could hardly be a reference to the wonderful arrival of Jesus.
