WHAT HAPPENED AT PENTECOST? WHAT'S THIS ALL ABOUT?

Pentecost in most Christian churches is May 19, but scripturally, it cannot take place until June 15. Where is the disconnect with the Bible? What is taking place and how does the Old Testament prophetically speak about this season? This teaching is full of information most Christians have no idea of.
