Because the fall festivals pertain to Jesus' second coming, it is not surprising that we find all of them in the book of Revelation, which describes the closing events of earth's history in so much detail. This outline matches each of the festivals with the fulfillment described in Revelation.
The name of each festival is a link to a page containing its description and reference in Leviticus.
The Feast of Trumpets: The seven trumpets in Revelation 8-9, 11.
Revelation 8 and 9 show seven angels receiving seven trumpets, and the first six trumpets are sounded. Just as the purpose of the Feast of Trumpets was to warn Israel of the approaching Day of Atonement, so the trumpets in Revelation are to warn the world of the approaching judgment of God: the first angel's message says, "Fear God, and give him glory, because the hour of his judgment has come."
In Israel's yearly cycle, the Feast of Trumpets occurred shortly before the Feast of Tabernacles, which celebrated the final harvest. Similarly, it is at the end of the seventh trumpet that the earth is harvested.
The Day of Atonement: The completion of the judgment.
It was on the Day of Atonement that the people were cleansed from sin (Leviticus 16:30). For Israel, this was the equivalent of the "close of probation." We should not think of this as the ominous time after which it is too late to find mercy with God; rather, we should look forward to it as the time when we will be sealed in a state of complete victory over our sinful nature.
The Day of Atonement was the one day in the whole year when the ark of the covenant was seen by human eyes (two, to be precise--those of the high priest). In Revelation 11:19, after the seventh angel sounds his trumpet, the ark of the covenant is revealed in Heaven for all to see.
The Feast of Tabernacles: The harvest of believers in Jesus Christ after the final great outpouring of the Holy Spirit.
The harvest takes place when the grain is ripe (Revelation 14:14-16). There is, unfortunately, also a harvest of grapes. The ripened grain represents those who have chosen to worship God and accept his salvation through Jesus Christ. The grapes represent those who have chosen to follow their own wickedness.
In Revelation 7, John sees two groups of people. The first, consisting of 144,000 servants of God--the firstfruits of the harvest, are those who will take the gospel to the whole world. The second, a numberless multitude, are those who obey to the call to worship their Creator. This multitude is represented by the ripened grain in Revelation 14.
