Nehemiah 8:16-18

16The people went out, brought back branches, and made shelters for themselves on each of their rooftops and courtyards, the court of the house of God, the square by the Water Gate, and the square by the Ephraim Gate.

17The whole community that had returned from exile made shelters and lived in them. The Israelites had not celebrated like this from the days of Joshua son of Nun until that day. And there was tremendous joy.

18Ezra read out of the book of the law of God every day, from the first day to the last. The Israelites celebrated the festival for seven days, and on the eighth day there was a solemn assembly, according to the ordinance.
