The annual festivals given to the Nation of Israel are summarized in Leviticus chapter 23. These festivals are prophetic pictures of the Messiah's actions for the salvation and redemption of mankind. The spring festivals are symbolic of the Messiah's first coming that occurred about two thousand years ago. This includes the atoning sacrifice made at Passover and His giving of the spirit to mankind at the time of Pentecost. Similarly, the fall festivals represent the second coming of the Messiah. The events of the second coming include the millennial kingdom, the great white throne judgment, the marriage of the lamb, and the new heavens and earth. The Day of Shouting is a time of shouting for joy because the Messiah will reign in His kingdom.
The Hebrew phrase from which the Day of Shouting is translated is 'Yom Teruah'. This phrase is variously translated into English as the Day of Shouting, Day of Trumpets, and Day of Noise Making. These translations are each based on the various uses of the word 'teruah' within Scripture. These uses all surround the concept of making noise or sound in celebration or alarm through the use of the voice, the ram's horn, or even the silver trumpets used at the Temple.
In Scripture, Numbers chapter 29 contains a summary of the Temple offerings and sacrifices involved with the Day of Shouting. This day is to be considered a Sabbath day of rest in which people gather together and do not work. The offerings of this day include one young bull, one ram, and seven yearling lambs on top of the normal daily and monthly offerings. There is also an offering of 1 goat for atonement of sin. The many offerings suggest the importance of this special day.
Shouting with joy comes on this day because it marks the end of the tribulation. The tribulation is a time of great persecution against the believers in the Messiah. It is a time during which there will be many that are martyred for their belief. The tribulation is a sign that the end of this age is coming soon.
Rev 20:4-6 KJVAnd I saw thrones, and they sat upon them, and judgment was given unto them: and I saw the souls of them that were beheaded for the witness of Jesus, and for the word of God, and which had not worshipped the beast, neither his image, neither had received his mark upon their foreheads, or in their hands; and they lived and reigned with Christ a thousand years. {5} But the rest of the dead lived not again until the thousand years were finished. This is the first resurrection. {6} Blessed and holy is he that hath part in the first resurrection: on such the second death hath no power, but they shall be priests of God and of Christ, and shall reign with him a thousand years.
Shouting with gladness comes from those who were martyred during the tribulation because it is the time of the first resurrection. This event is mentioned in Revelation 20:4-6 in which new life is given to those who have stood strong in the Messiah and have received this special reward. They do not have to wait until the Great White Throne judgment to receive new life and the second death has no power over them.
Shouting in celebration comes from believers because this day also marks the beginning of the Millennial Kingdom. The millennial kingdom is the one thousand year reign of the Messiah before He places everything back into His Father's hands. During this time, all nations will obey and know that He is the king. While the first coming showed the Messiah as a suffering servant, the second coming will show Him as a conquering King who will place all things under His feet.
Heb 8:1-5 KJVNow of the things which we have spoken this is the sum: We have such an high priest, who is set on the right hand of the throne of the Majesty in the heavens; {2} A minister of the sanctuary, and of the true tabernacle, which the Lord pitched, and not man. {3} For every high priest is ordained to offer gifts and sacrifices: wherefore it is of necessity that this man have somewhat also to offer. {4} For if he were on earth, he should not be a priest, seeing that there are priests that offer gifts according to the law: {5} Who serve unto the example and shadow of heavenly things, as Moses was admonished of God when he was about to make the tabernacle: for, See, saith he, that thou make all things according to the pattern showed to thee in the mount.
The reign of the Messiah will take place from the Heavenly Temple. There, as pictured in Hebrews 8:1-5, He is the great high priest acting on behalf of mankind towards the Heavenly Father. Those who are raised in the first resurrection also receive the blessing of being able to act as priests under the Messiah for the thousand years of His reign.
Shouting with triumph also comes because of another event. As described in Revelation 20:1-3, the angel will come, bind Satan, and throw him into the bottomless pit. This will remove his evil actions and influence from the world and it will last until near the end of the thousand years.
