The Feast of Tabernacles begins on the fifteenth day of the seventh month. It lasts for seven days. The first of seven days is a Holy Day of convocation. In the fifteenth day of the seventh month, when ye have gathered in the fruit of the land, ye shall keep a feast unto the Lord seven days: on the first day shall be a Sabbath, and on the eighth day shall be a Sabbath [Last Great Day]. And ye shall take you on the first day the boughs of goodly trees, branches of palm trees, and the boughs of thick trees, and willows of the brook; and ye shall rejoice before the Lord your God seven days.” (Leviticus 23:39-40)
The Feast of Tabernacles points to the time of the establishment of the Kingdom of God on earth. Jesus Christ – the Messiah – will be ruling over an earth becoming perfect for one-thousand years. We will reign and rule with Him.
