Nehemiah 8:16-17

So the people went out and got tree branches. They built shelters on their roofs, in their courtyards, in the courtyards of the Temple, in the square by the Water Gate, and in the square next to the Gate of Ephraim. The whole group that had come back from captivity built shelters and lived in them. The Israelites had not done this since the time of Joshua son of Nun. And they were very happy.
