Leviticus 23:33-36 - The Feast Of Booths
33 And the LORD spoke unto Moses, saying, 34 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. 35 On the first day shall be a holy convocation: you shall do no regular work on it. 36 Seven days you shall offer an offering made by fire unto the LORD: on the eighth day shall be a holy convocation unto you; and you shall offer an offering made by fire unto the LORD: it is a solemn assembly; and you shall do no regular work on it.
