Nehemiah 8:14-17

8:14 They discovered written in the law that the LORD had commanded through Moses that the Israelites should live in temporary shelters during the festival of the seventh month, 8:15 and that they should make a proclamation and disseminate this message in all their cities and in Jerusalem: “Go to the hill country and bring back olive branches and branches of wild olive trees, myrtle trees, date palms, and other leafy trees to construct temporary shelters, as it is written.”

8:16 So the people went out and brought these things back and constructed temporary shelters for themselves, each on his roof and in his courtyard and in the courtyards of the temple of God and in the plaza of the Water Gate and the plaza of the Ephraim Gate. 8:17 So all the assembly which had returned from the exile constructed temporary shelters and lived in them. The Israelites had not done so from the days of Joshua son of Nun until that day. Everyone experienced very great joy.
