SUKKOT (Feast of Tabernacles) is also called the Feast of Ingathering (Lev 23:3 9). To celebrate this festival, GOD commanded the Israelites to dwell in booths for seven days so that they would remember that He provided shelter and security for their ancestors during their exodus from Egypt.
The seventh chapter of John gives on account of the Messiah Yeshua attending Sukkot in Jerusalem. In the midst of the Festival, Yeshua went into the Temple to teach and His words were received by many, and rejected by others. The Jewish people were divided in their opinion as to whether Yeshua was the Messiah. He gave His answer to their doubts on the Last day of Sukkot (Hoshana Rabah), when He stood up and proclaimed "If any man thirst, let him come unto Me and drink. He that believes in me as the scripture says, out of his heart shall flow rivers of living water." (John 7:37-38). Many believed in Him after that time.
The scriptures teach of a future role for the feast of Sukkot in the plan of GOD. Zechariah 12-14 tells of the final climactic battle of the nations against Israel. Zechariah also prophesied that Israel would accept their Messiah in those days and that the LORD would save them from total destruction. In the Messianic reign, the nations will then be required to keep the Feast of Tabernacles (Sukkot) by coming up to Jerusalem to offer their sacrifices and worship the King of Kings, Yeshua the Messiah.
