The seven-day Feast of Tabernacles is also known as the Feast of Ingathering (Leviticus 23:34; Exodus 23:16) and is called Sukkot by the Jews today. This festival pictures the 1,000-year rule of Jesus Christ on this earth, known as the Millennium (Revelation 20:4-6). Isaiah describes this future period as a time of peace when God’s law will go forth to all nations from Jerusalem (Isaiah 2:2-4).
With the coming of world peace, countries will “beat their swords into plowshares, and their spears into pruning hooks; nation shall not lift up sword against nation, neither shall they learn war anymore” (Isaiah 2:4; Micah 4:3).
The rivers represent the healing waters mentioned in Ezekiel 47, Joel 3: 18 and in Zechariah 14: 8 “On that day living water will flow out from Jerusalem, half of it east to the Dead Sea and half of it west to the Mediterranean Sea, in summer and in winter.”
Isaiah 35:5-6 prophecies of this time during which “the eyes of the blind shall be opened, and the ears of the deaf unstopped. Then shall the lame leap like a deer, and the tongue of the mute sing for joy” (ESV).
People from all nations will go up to Jerusalem to celebrate the Feast of Tabernacles during the millennium. “And it shall come to pass that everyone who 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).
