Tomorrow is Pentecost, one of three of the required special Sabbaths in the Bible... Each of these three festivals are a week long!  God actually intended his people to have 52 Sabbath's off a year, 3 weeks of vacation, plus a few others!   NICE BOSS!

"Astounding!" "Dumbfounding!" "What is the meaning of this?" "What is happening?" These were the startled expressions coming from the mouths of a crowd of several thousand on the Day of Pentecost nearly two thousand years ago. Those who uttered these words of astonishment were mostly Jews and proselytes, with a sprinkling of Romans and other gentiles among them, who were gathered in Jerusalem for the Feast of Weeks, or the fiftieth day following the offering of the wave sheaf. All knew it was the "Feast of the Firstfruits," and that it was celebrated "on the morrow after the seventh Sabbath" following the wave sheaf ceremony. But none had the slightest inkling of what was to happen on this momentous day. They were shocked, startled, puzzled! Then, by the thousands, they tearfully crowded around Christ's apostles, asking to be baptized! They repented in droves at the inspired preaching of the apostles, who wore flickering, brilliant crowns of flame! Read, in your own Bible, of the miracles that took place on the first Pentecost after Christ's resurrection––of the miracle of Pentecost!

       A swarthy trader from Egypt, who was half Jewish, began speaking in a sardonic whisper to the Arabian standing next to him. "They have got to be drunk with new wine!" he said.
      The Arabian watched as the trader made a circling motion around his head with his index finger and rolled his eyes derisively. He didn't understand a word the Egyptian–Jew had said, but he got the message.
      A Phrygian camel driver laughed, gestured toward the disciples who were in full view, and said, "I'd like to know how they do it--I mean, how is it that they manage to have all those flames flickering around their heads, and not a hair singed?"
      Neither of the other men understood the Phrygian, until a Levite from Media, who was skilled in all three languages, translated for each of them.
      "They can't be drunk, seeing it's only about 9:00 in the morning, and there isn't a wineshop open in the city--but tell me this, how is it that each of you are understanding what these men have been saying, when they are speaking in my language?"
      The Egyptian looked startled, and the Arabian's mouth dropped open. The Phrygian camel driver laughed, "Oh, no. Impossible! They, every one of them, have been speaking in my tongue--which is surprising, for not many in Jerusalem know the dialect of Phrygia!"
      The word had spread like wildfire throughout the city: "A miracle! A miracle! Some of the followers of that man Jesus, who claimed to be the Messiah, are standing there with their hair on fire, and speaking in about sixteen different languages and all of us are hearing them in our own dialect!"
      When the excited babble of voices came to Peter, after most of the other disciples had addressed the crowd, Peter stood up, gestured for silence. His hair was blazing; flickering tongues of flame were leaping over his head like a golden corona; yet, there was no damage to his head or hair!
      "Men of Judaea, and all of you who live in Jerusalem, let this be understood! Listen to my words! These men are not drunken, like you think they are, seeing it is only the third hour of the day.
      "But this is that which was spoken by the prophet Joel; 'And it shall come to pass in the last days, saith God, I will pour out of my Spirit upon all flesh: and your sons and daughters shall prophesy, and your young men shall see visions, and your old men shall dream dreams: And on my servants and on my handmaidens I will pour out in those days of my Spirit; and they shall prophesy.'"
      The Phrygian nudged the Arabian, who looked at the Median Levite. "Did you understand that?" The Phrygian asked no one in particular. The linguist from Media rapidly asked each the same question, and all nodded vigorously, their eyes wide with wonderment.
      "Something is going on here--something I can't explain!" the Levite said to them. "We'd better listen!"
      Can any of us truly imagine what it must have been like for the large crowd of people from all over the Mediterranean world to have been assembled in Jerusalem on that momentous day? Can we picture, for even a moment, the astonishing sight, the astounding words that were spoken, or the excitement and wonderment that swept over the audience?
      One of the most stupendous miracles of all time was taking place before their astonished eyes, and filling their ears. It was the miracle of Pentecost, when God's Holy Spirit was first made available to the human race; when the "other Comforter" Jesus Christ promised (John 14:26) was sent to mankind.
