The Feast of Tabernacles, also known as the Feast of Booths or Sukkot, is a biblical festival that is described in several passages in the King James Version of the Bible. One of the key references to the Feast of Tabernacles is found in Leviticus 23:33-36:

“And the LORD spake unto Moses, saying, Speak unto the children of Israel, saying, The fifteenth day of this seventh month shall be the feast of tabernacles for seven days unto the LORD. On the first day shall be a holy convocation: ye shall do no servile work therein. Seven days ye shall offer an offering made by fire unto the LORD: on the eighth day shall be an holy convocation unto you; and ye shall offer an offering made by fire unto the LORD: it is a solemn assembly; and ye shall do no servile work therein.”

This passage instructs the Israelites to observe the Feast of Tabernacles for seven days, starting on the fifteenth day of the seventh month. The first day and the eighth day (which follows the seven days) are considered holy convocations or special gatherings. During the feast, offerings were made by fire to the Lord, and the people were to refrain from doing any regular work. The Feast of Tabernacles is associated with remembering the time when the Israelites dwelled in temporary shelters or booths during their journey in the wilderness after the Exodus from Egypt.

Other references to the Feast of Tabernacles can be found in Deuteronomy 16:13-15 and Nehemiah 8:13-18, among other passages in the Bible.
