Meaning of the Feast of Tabernacles
In the Bible, people are sometimes referred to as wood (Jeremiah 5:14), and the people of God are considered temple material (Revelation 3:12). During the Feast of Tabernacles, which is also called the Feast of Ingathering, temple materials are joyfully gathered and presented to God; the New Covenant is preached and all those willing to hear come to receive the Holy Spirit.
On the last and most important day of the feast [of Tabernacles] Jesus stood up and said in a loud voice, “Let anyone who is thirsty come to me and drink. If anyone believes in me, rivers of living water will flow out from that person’s heart, as the Scripture says.” Jesus was talking about the Holy Spirit.
