A:
The Septuagint is a flawed early Greek translation of the Hebrew scriptures. One of the many mistakes in the Septuagint is to mistranslate Isaiah 7:14, creating the opportunity to interpret this as a prophecy that Jesus would be born of a virgin.
What the prophet Isaiah actually wrote in the original Hebrew was, "Therefore the Lord himself shall give you a sign; Behold, the young woman shall conceive, and bear a son, and shall call his name Immanuel." The Septuagint says instead: "Therefore the Lord himself shall give you a sign; Behold, a virgin shall conceive, and bear a son, and shall call his name Immanuel." Although this does not actually mention Jesus (even saying that the son will be called Immanuel), nor provide any information from which to identify Jesus indirectly, the author of Matthew's Gospel used this passage to demonstrate that the birth of Jesus had already been prophesied by Isaiah.

This gathering was a time for prayer, reflection, and unity among the disciples after His resurrection and before His ascension.

The Apostles through the Holy Spirit lead to the spread of teaching about Christ (Immanuel), there were no three specific groups involved, I'm not sure where you picked that up. Paul mentions his responsibility to teach two groups in Romans 9 & 10. However there are not three specific groups which lead to the spread of Christianity,The 12 Apostles and the Holy Spirit hold the responsibility for spreading the gospel "good news" of the coming of Immanuel (Jesus Christ) as it was foretold to the prophet Isaiah 7:14. This still holds true today as the Apostles continue to speak from that written word and spread the good news (gospel), concerning the coming of Immanuel (Jesus Christ).
