Leviticus 23:33-44

Again the LORD spoke to Moses, saying, “Speak to the sons of Israel, saying, ‘On the fifteenth of this seventh month is the Feast of Booths for seven days to the LORD. On the first day is a holy convocation; you shall do no laborious work of any kind. For seven days you shall present an offering by fire to the LORD. On the eighth day you shall have a holy convocation and present an offering by fire to the LORD; it is an assembly. You shall do no laborious work. ‘These are the appointed times of the LORD which you shall proclaim as holy convocations, to present offerings by fire to the LORD—burnt offerings and grain offerings, sacrifices and drink offerings, each day’s matter on its own day— besides those of the sabbaths of the LORD, and besides your gifts and besides all your votive and freewill offerings, which you give to the LORD. ‘On exactly the fifteenth day of the seventh month, when you have gathered in the crops of the land, you shall celebrate the feast of the LORD for seven days, with a rest on the first day and a rest on the eighth day. Now on the first day you shall take for yourselves the foliage of beautiful trees, palm branches and boughs of leafy trees and willows of the brook, and you shall rejoice before the LORD your God for seven days. You shall thus celebrate it as a feast to the LORD for seven days in the year. It shall be a perpetual statute throughout your generations; you shall celebrate it in the seventh month. You shall live in booths for seven days; all the native-born in Israel shall live in booths, so that your generations may know that I had the sons of Israel live in booths when I brought them out from the land of Egypt. I am the LORD your God.’ ” So Moses declared to the sons of Israel the appointed times of the LORD.
