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 an 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.- LEVITICUS 23:33-36
YE SHALL KEEP IT A FEAST
And ye shall keep it a feast unto the Lord seven days in the year. It shall be a statute for ever in your generations: ye shall celebrate it in the seventh month. Ye shall dwell in booths seven days; all that are Israelites born shall dwell in booths: That your generations may know that I made the children of Israel to dwell in booths, when I brought them out of the land of Egypt: I am the Lord your God.-Leviticus 23:41-43
