The Feast of Trumpets or Rosh Hashanah
Observance:
As ordained by God, the Feast of Trumpets was to be observed on Tishrei 1.
Because this feast falls on the first day of the Jewish civil calendar, it is seen as a type of “New Years Day” for Israel. Traditionally, it is believed that Adam (mankind) was created on this day. Some also believe that Jesus, who is called the “Second Adam” (1 Corinthians 15:45) So it is written: “The first man Adam became a living being”; the last Adam, a life-giving spirit.) was born on this day.
The biblical record for observance of the feast is very simple: it was to be kept as a Sabbath day of rest and memorialized by the blowing of the trumpets, both in the Temple and throughout the land (Leviticus 23:23-25).
Future Fulfillment
According to tradition, the trumpet would be blown one hundred times at the Feast of Trumpets. The hundredth, or final, trumpet blast was known as the “last trump.” In the Bible, the last trump is associated with the resurrection/rapture of believers at the end of the age: “In a moment, in the twinkling of an eye, at the last trump…. The dead shall be raised incorruptible, and we shall be changed” (1 Corinthians 15:52)
The Torah refers to the Feast of Trumpets as, Yom Teruah, or the “day of awakening blast.” In Isaiah, an awakening blast is associated with the resurrection/rapture event: “Your dead will live…You who lie in the dust, awake and shout for joy” (Isaiah 26:19)
In addition to “resurrection,” the Bible associates the blowing of trumpets with other types of actions. One of these is the gathering of the assembly before God: “When they shall blow [the trumpets] with them, all the assembly shall assemble themselves to thee at the door of the tabernacle” (Numbers 10:3). This gathering of an assembly before the tabernacle (God’s dwelling place) typifies the Rapture, which will be a “gathering” of God’s people before the throne: “I looked, and there before me was a great multitude that no one could count, from every nation, tribe, people and language, standing before the throne and before the Lamb” (Revelation 7:9)
The blowing of the trumpets is also associated with the sounding of an “alarm” in Scripture: “If ye go to war in your land against the enemy that oppresseth you, then ye shall blow an alarm with the trumpets; and ye shall be remembered before the LORD your God, and ye shall be saved from your enemies” (Numbers 10:9). The sounding of an alarm to go to war against an oppressor (the devil) also typifies the Rapture: Joel 2 we see the “alarm” (trumpet) being sounded as the Day of the Lord (commencing just after the Rapture) nears: “Blow the trumpet in Zion; sound the alarm on my holy hill. Let all who live in the land tremble, for the day of the LORD is coming” (Joel 2:1).
Rapture in that the trumpet blast on the Feast of Trumpets, will declare Jesus’ kingship!
