Jewish month of Tishri is the beginning and the end. It is the first month on the civil calendar with Creation.  Tishri means beginning. The Bible begins with Genesis or Aleph b'Tishri. Jewish tradition says Adam was created on the 1st of Tishri. God created the world in six days and rested the seventh so man rules 6000 years and Jesus Christ rules 1000 years. Tishri is the seventh month on the religious calendar. When time comes full circle, Tishri ends with Trumpets, Atonement and begins again with Tabernacles, God with us.

In the beginning [On the first of Tishri], God created the heaven and the earth (Genesis 1:1).

Trumpets

The Feast of Trumpets is on the 1st of Tishri. It literally means the day of shouting. The new year begins after the first sighting of the new moon. Since lunar months are 29 or 30 days and set by observation, no one knew the day or hour until two witnesses see the first sliver of the crescent moon and testify before the Sanhedrin (Matthew 24:36). In the synagogue, the shofar is sounded a hundred times and the last trump is the Tekiah Gedolah (1 Corinthians 15:52). Being devout Jews, Jesus and Paul point to Trumpets as the resurrection and rapture day.

For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first: Then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord (1 Thessalonians 4:15-17).

Day of Atonement

The Day of Atonement is on the 10th of Tishri and is the most holy day of the year. This is the only day the High Priest enters the temple's Holy Place. He sacrifices a ram, bull and goat then sprinkles the blood on the Ark of the Covenant. This is a day of national repentance and forgiveness for the sins of Israel. The Jewish people observe a twenty-five hour fast of food and water. Atonement is fulfilled on the Second Coming as Jesus Christ rescuses the Saints and redeems Israel.

I [God] will pour upon the house of David, and upon the inhabitants of Jerusalem, the spirit of grace and of supplications: and they shall look upon me whom they have pierced, and they shall mourn for him, as one mourns for his only son, and shall be in bitterness for him, as one that is in bitterness for his firstborn (Zechariah 12:10).

Tabernacles

The Feast of Tabernacles is from the 15th to the 21st of Tishri. It is a joyous celebration of the presence of God. On Tabernacles, the first Jewish temple was dedicated by Solomon and the Spirit of God entered the temple. Jesus Christ was conceived on Hanukkah but was born on Tabernacles. God the Father dwelt in the tabernacle and temple, God the Son dwelt with humanity as a man and during the future Millennium as God and the Holy Spirit dwells within His people. During Tabernacles, the people live in booths. Tabernacles is the week long coronation of Jesus Christ as King of Kings.

Behold, the tabernacle of God is with men, and he will dwell with them, and they shall be his people, and God himself shall be with them, and be their God (Revelation 21:3).

The fall holy days are prophesies of future events. Trumpets is the resurrection and rapture of the Church. The Day of Atonement is the confirmation of the covenant that begins the Tribulation and seven years later is the Second Coming of Jesus Christ. The Feast of Tabernacles is the birth of Jesus Christ and coronation of the King of Kings and Lord of Lords.

Every one that is left of all the nations which came against Jerusalem shall go up from year to year to worship the King, the Lord of hosts, and to keep the feast of tabernacles (Zechariah 14:16).
