Nehemiah 8:16-17

So the people went out and cut branches and used them to build shelters on the roofs of their houses, in their courtyards, in the courtyards of God’s Temple, or in the squares just inside the Water Gate and the Ephraim Gate. So everyone who had returned from captivity lived in these shelters during the festival, and they were all filled with great joy! The Israelites had not celebrated like this since the days of Joshua son of Nun.
