We are told that the new moon and the Feasts of the Lord are a shadow of things to come in
Colossians 2: Let no man therefore judge you in meat, or in drink, or in respect of an holyday, or of the new moon, or of the sabbath days:
 Which are a shadow of things to come; but the body is of Christ.
The Feast of Trumpets is the only Feast of the Lord that falls on a new moon so it in particular is mentioned in the verses.
The first four Spring feasts were fulfilled at Christ’s first coming, and on the exact day of the feast. The remaining 3 feasts of Fall picture the Second Coming of Christ of which the Feast of Trumpets is the first picturing the rapture and is a memorial to Israel.
Let us look at some of the Jewish teaching about the Feast of Trumpets.
The Jews call it the feast of memorial with the blowing of the trumpets and the creation took place on this day (though some teach it to be the day of the creation of Adam and Eve). They also believe it to be the day of the binding of Isaac for sacrifice.
The Feast of Trumpets happens on the “new moon”, which is 29.5 days after the last one, meaning it might occur on the 29th or 30th day, nobody knows for sure. It is called “the day that no man knoweth“ In reference to His return Jesus made this statement:
Matt.24: But of that day and hour knoweth no man, no, not the angels of heaven, but my Father only.”
Of that day or hour no man knows” is also an expression referring the Jewish groom uses when asked when his impending wedding is going to happen. The Jewish custom is when the father of the groom determines a place is ready for the groom’s bride he will tell the son to go and get her.
In Ephesians 5 it is revealed the church is the Bride of Christ.
Ephesians 5: For we are members of his body, of his flesh, and of his bones.
 For this cause shall a man leave his father and mother, and shall be joined unto his wife, and they two shall be one flesh.
 This is a great mystery: but I speak concerning Christ and the church.
 Nevertheless let every one of you in particular so love his wife even as himself; and the wife see that she reverence her husband.
The Jews teach their were two trumpets made by Abraham of the horns of the ram slain in Isaac’s place. One of these they call the Great Trump and the other the Last Trump. They teach the Last Trump is the one blown at the beginning of the Feast of Trumpets.
1Cor.15: In a moment, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed.
The Jews teach two witnesses were required to see the new moon and report the sighting to the priest who then blew the last trump. In Revelation we are taught there will be two witnesses appear at the beginning of the time of Tribulation Note they are olive trees. In Romans 11 we are taught the church is a part of the olive tree (not the fig tree) of Israel. The olive harvest occurs during the time of the Feast of Trumpets.
Rev.11:3 And I will give power unto my two witnesses, and they shall prophesy a thousand two hundred and threescore days, clothed in sackcloth.
 These are the two olive trees, and the two candlesticks standing before the God of the earth.
 And if any man will hurt them, fire proceedeth out of their mouth, and devoureth their enemies: and if any man will hurt them, he must in this manner be killed.
 These have power to shut heaven, that it rain not in the days of their prophecy: and have power over waters to turn them to blood, and to smite the earth with all plagues, as often as they will.
 And when they shall have finished their testimony, the beast that ascendeth out of the bottomless pit shall make war against them, and shall overcome them, and kill them.
The Jews teach when the Last Trump is blown the doors of Heaven are opened and the books are also opened. The names of the righteous are immediately sealed, the wicked blotted out and the intermediate are given 10 days (inclusive) to repent.
Ezekiel 46:1 Thus saith the Lord GOD; The gate of the inner court that looketh toward the east shall be shut the six working days; but on the sabbath it shall be opened, and in the day of the new moon it shall be opened.
Revelation 4:1 After this I looked, and, behold, a door was opened in heaven: and the first voice which I heard was as it were of a trumpet talking with me; which said, Come up hither, and I will shew thee things which must be hereafter.
Revelation.5:1 And I saw in the right hand of him that sat on the throne a book written within and on the backside, sealed with seven seals.
 And I saw a strong angel proclaiming with a loud voice, Who is worthy to open the book, and to loose the seals thereof?
 And no man in heaven, nor in earth, neither under the earth, was able to open the book, neither to look thereon.
 And I wept much, because no man was found worthy to open and to read the book, neither to look thereon.
 And one of the elders saith unto me, Weep not: behold, the Lion of the tribe of Juda, the Root of David, hath prevailed to open the book, and to loose the seven seals thereof.
Revelation 7:1 And after these things I saw four angels standing on the four corners of the earth, holding the four winds of the earth, that the wind should not blow on the earth, nor on the sea, nor on any tree.
 And I saw another angel ascending from the east, having the seal of the living God: and he cried with a loud voice to the four angels, to whom it was given to hurt the earth and the sea,
 Saying, Hurt not the earth, neither the sea, nor the trees, till we have sealed the servants of our God in their foreheads.
 And I heard the number of them which were sealed: and there were sealed an hundred and forty and four thousand of all the tribes of the children of Israel.
 Of the tribe of Juda were sealed twelve thousand. Of the tribe of Reuben were sealed twelve thousand. Of the tribe of Gad were sealed twelve thousand.
 Of the tribe of Aser were sealed twelve thousand. Of the tribe of Nepthalim were sealed twelve thousand. Of the tribe of Manasses were sealed twelve thousand.
 Of the tribe of Simeon were sealed twelve thousand. Of the tribe of Levi were sealed twelve thousand. Of the tribe of Issachar were sealed twelve thousand.
 Of the tribe of Zabulon were sealed twelve thousand. Of the tribe of Joseph were sealed twelve thousand. Of the tribe of Benjamin were sealed twelve thousand.
 After this I beheld, and, lo, a great multitude, which no man could number, of all nations, and kindreds, and people, and tongues, stood before the throne, and before the Lamb, clothed with white robes, and palms in their hands;
 And cried with a loud voice, saying, Salvation to our God which sitteth upon the throne, and unto the Lamb.
 And all the angels stood round about the throne, and about the elders and the four beasts, and fell before the throne on their faces, and worshipped God,
The greeting for the Feast of Trumpets is “may you be inscribed and sealed for a good year”
Please note the sealing of the righteous Jews and the appearance of the Gentile masses appear to occur simultaneously.
The traditional service for dashiki (casting off) is recited individually and includes the prayer of
Micah 7:18 Who is a God like unto thee, that pardoneth iniquity, and passeth by the transgression of the remnant of his heritage? he retaineth not his anger for ever, because he delighteth in mercy.

 Thou wilt perform the truth to Jacob, and the mercy to Abraham, which thou hast sworn unto our fathers from the days of old.”Who is like unto you, O God.…..And You will cast all their sins into the depths of the sea”
Michael the archangel whose name means “Who is like unto God?” is the definition of the archangel Michael’s name which calls to mind Daniel 12:1.
Daniel12: And at that time shall Michael stand up, the great prince which standeth for the children of thy people: and there shall be a time of trouble, such as never was since there was a nation even to that same time: and at that time thy people shall be delivered, every one that shall be found written in the book.

The Jews teach the Feast of Trumpets is known as the Wedding of the Messiah, and the Church is the Bride of Christ, (Ephesians 5) and the rapture is when the Church is caught up to heaven to be wed with Christ. (1 Corinthians 15)
The Jewish wedding consist of the groom coming to get his bride and then they are sequestered for 7 days at the end of which the groom presents his bride to the wedding party along with the bloodied napkin proving her virginity to those present.
Revelation 19:6 And I heard as it were the voice of a great multitude, and as the voice of many waters, and as the voice of mighty thunderings, saying, Alleluia: for the Lord God omnipotent reigneth.
 Let us be glad and rejoice, and give honour to him: for the marriage of the Lamb is come, and his wife hath made herself ready.
 And to her was granted that she should be arrayed in fine linen, clean and white: for the fine linen is the righteousness of saints.

 And he was clothed with a vesture dipped in blood: and his name is called The Word of God.
 And the armies which were in heaven followed him upon white horses, clothed in fine linen, white and clean.
There are seven days of awe, which is to be a time of repentance, (note the continued theme in Revelation of the world not repenting) between the Feast of Trumpets and the Day of Atonement. These picture the seven years of Tribulation. If you add the two-day Trumpets feast, and the Day of Atonement, the 7 days of awe are “ten days of tribulation” which are referred to in Revelation 2:10.
