Nehemiah 8:17-18

The 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. Ezra 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.
