Leviticus 23:33-36 Again the LORD spoke to Moses, saying, “Speak to the sons of Israel, saying, ‘On the fifteenth of this seventh month is the Feast of Booths for seven days to the LORD. On the first day is a holy convocation; you shall do no laborious work of any kind. For seven days you shall present an offering by fire to the LORD. On the eighth day you shall have a holy convocation and present an offering by fire to the LORD; it is an assembly. You shall do no laborious work.’”
On our western Gregorian calendar in 2026, the Feast of Tabernacles will be observed from about Friday, September 25th to Friday, October 2th (Great Day). Or pending the new moon confirmed at the beginning of the Hebrew month of Tishri.
This year, the Essenes mark the beginning of Tabernacles on Wednesday, September 30th and runs through Tuesday, October 6th. The last and Great Day occurs on Wednesday, October 7th.
The third and last fall holiday on God’s calendar is Tabernacles. It is also called Sukkot, the Feast of Booths, the Festival of Tents, or the Feast of the Harvest because it was after the harvest in the fall. Simply put, it was also called “the Feast” or “the Festival”. This festival is a week-long festival from Tishri 15 to 21 on a Hebrew calendar.
Jews sing Isaiah 12:3 Therefore you will joyously draw water from the springs of salvation, during the Feast of Tabernacles or Sukkot.
The Jewish holiday is a reminder to the Jewish people they lived in tents after the Exodus from Egypt.
In addition, the Feast of Tabernacles requires sacrifices of sin offerings and burnt offerings. At the time of preparation for the morning sacrifice, a priest descends to the Pool of Siloam amidst great music, celebration, and singing of Isaiah 12:3, and fills a golden pitcher with water. After dipping his pitcher in Siloam’s water, the priest returns to the Temple and pours the water into one of the silver basins by the altar (Wayne Stiles, Insight for Living).
Jesus connects the dots for us in the Book of John. He is promising those who believe in Him the Holy Spirit. Jesus is making this proclamation on the last day of the Jewish holiday of Sukkot.
John 7:37-39 Now on the last day, the great day of the feast, Jesus stood and cried out, saying, “If anyone is thirsty, let him come to Me and drink. He who believes in Me, as the Scripture said, ‘From his innermost being will flow rivers of living water.’” But this He spoke of the Spirit, whom those who believed in Him were to receive; for the Spirit was not yet given, because Jesus was not yet glorified.
This chapter of Isaiah is a universal promise to the entire world. The Holy One, Jesus is our salvation. Isaiah 12 refers to the promise of the Holy Spirit and the reign of Jesus. And He is going to live and dwell with us.
John 4:14 “…but whoever drinks of the water that I will give him shall never thirst; but the water that I will give him will become in him a well of water springing up to eternal life.”-Jesus
