Leviticus 23:33

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

SUCCOTH (booths). This feast is the one called Succoth by the Jews, due to the requirement that people should live in booths, thus remembering the times when they were in slavery and in the times of their journeys in the wilderness. It came at the conclusion of the annual harvest and was also called the Harvest Festival. The booths were constructed much after the manner of the brush arbors that were widely used for the church in the early part of this century as outdoor gathering places where the gospel was preached.
