Leviticus 23:33-36 - The Feast Of Booths
33 And LORD spoke to Moses, saying, 34 Speak to the sons of Israel, saying, On the fifteenth day of this seventh month is the feast of tabernacles for seven days to LORD. 35 On the first day shall be a holy convocation. Ye shall do no servile work. 36 Seven days ye shall offer an offering made by fire to LORD. On the eighth day shall be a holy convocation to you, and ye shall offer an offering made by fire to LORD. It is a solemn assembly; ye shall do no servile work.
