We pick up our study through the book of Acts in Acts 2:5 today.
VERSE 5: And there were dwelling at Jerusalem Jews, devout men, out of every nation under heaven. Notice that this verse tells us that those who were present were only Jews. These Jews were men who had come out of every nation under heaven to Jerusalem for the mandatory feast days. These included Pesach (Passover), Shavuot (Weeks or Pentecost), and Sukkot (Tabernacles or Booths). At this point, we must remember that the Jews had been scattered to the nations as a result of the diaspora (the dispersion) after the fall of the Northern Kingdom in 723 BC. There was also no doubt some expectations in regard to the messianic prophecies that were most likely fueled by possibly the wise men who had come earlier, Simion's statement in Luke 2:25, and maybe the study of the faithful in regards to Daniel's prophecies in Daniel 9:24-27. Jerusalem must have been abuzz.
VERSES 6-11: Now when this was noised abroad, the multitude came together, and were confounded, because that every man heard them speak in his own language. And they were all amazed and marvelled, saying one to another, Behold, are not all these which speak Galilaeans? And how hear we every man in our own tongue, wherein we were born? Parthians, and Medes, and Elamites, and the dwellers in Mesopotamia, and in Judaea, and Cappadocia, in Pontus, and Asia, Phrygia, and Pamphylia, in Egypt, and in the parts of Libya about Cyrene, and strangers of Rome, Jews and proselytes, Cretes and Arabians, we do hear them speak in our tongues the wonderful works of God. Immediately what happened was noised abroad. The term has nothing to do with the modern sense of abroad. The sense here is that of a rumor.
Notice the multitude in v.6. This is referring to the Jews that were just mentioned in v.5. They were amazed and marveled because all of those filled with the Holy Ghost and speaking in other tongues were Galileans, but each of them was hearing in their native tongues in which they were born. Remember, these Jews were from all over the known world who were in Jerusalem for the feasts. Notice that everyone present for this event were Jewish, either naturally born or proselytes (v. 10). In other words, this was not a Gentile event.
VERSES 12-13: And they were all amazed, and were in doubt, saying one to another, What meaneth this? Others mocking said, These men are full of new wine. Notice that there are two responses to this event: those who doubted and those who mocked. On a side note, that is exactly what happens today in regards to how people respond to God. The word doubt more so implies that they were perplexed more than that of being skeptical. They simply did not know what was going on. On the other hand, the mockers out-of-hand rejected the event as being a work of God.
VERSES 14-15: But Peter, standing up with the eleven, lifted up his voice, and said unto them, Ye men of Judaea, and all ye that dwell at Jerusalem, be this known unto you, and hearken to my words: For these are not drunken, as ye suppose, seeing it is but the third hour of the day. At this point, Peter, being the designated spokesman for the group, as appointed by Christ himself in Matthew 16:17-19, stands up to explain just what is going on. And notice, who he is addressing. He is addressing the Jews that had assembled in Jerusalem and had just witnessed this outpouring of the Holy Spirit. His first concern was to refute the mockers who had assumed that the event had occurred because of drunkenness.
