Nehemiah 8:16-18

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. 8:18 Ezra read in the book of the law of God day by day, from the first day to the last. They observed the festival for seven days, and on the eighth day they held an assembly as was required.
