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