Trumpets of God
In Judaism there are three trumpets which have been given names:
There is the "first trumpet" which was sounded at Mount Sinai (Ex. 19:16):
"Then it came to pass on the third day, in the morning, that there were thunderings and lightnings, and a thick cloud on the mountain; and the sound of the trumpet was very loud, so that all the people who were in the camp trembled."
Then there is the "last trumpet", which the Jewish people believe will sound on some future the Feast of Trumpets (Rosh Hashanna). When that happens, Messiah will come, the dead will be resurrected and be judged with the living. This is the trumpet to which the Apostle Paul alluded to in I Cor. 15:
:51"Behold, I tell you a mystery: We shall not all sleep, but we shall all be changed-
:52 in a moment, in the twinkling of an eye, at the last trumpet. For the trumpet will sound, and the dead will be raised incorruptible, and we shall be changed."
Jewish people believe in a common resurrection whereby, Messiah will come forth in the earth, and resurrect the righteous and the wicked together, then pass final judgment upon each one.
Christians, on the other hand, reckon the last trumpet to be the signal by which Messiah, will come from heaven, and resurrect only the dead who have trusted in Him. These will then be raptured to heaven, with the translated living church to appear before the judgment seat of Christ, which is in heaven (Rom. 14:10).
Finally, there is the "great trumpet" (the shofar Haggado). This is the one which normally sounds at the closing ceremony, called Ne'ila, to announce the end of the Day of Atonement each year.
Among many Christians, it is believed to refers to the Revelation of Jesus Christ, and the ingathering of the tribulational elect from the four winds of the earth, with "...the great sound of a trumpet..." (Matt. 24:31).
