Nehemiah 8:1-3, 16

All the people of Israel gathered together in the square by the Water Gate. They asked Ezra the teacher to bring out the Book of the Teachings of Moses, which the LORD had given to Israel. So on the first day of the seventh month, Ezra the priest brought out the Teachings for the crowd. Men, women, and all who could listen and understand had gathered. At the square by the Water Gate Ezra read the Teachings out loud from early morning until noon to the men, women, and everyone who could listen and understand. All the people listened carefully to the Book of the Teachings.

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.
