Nehemiah 8:14-18

14As they studied the Law, they discovered that the Lord had commanded through Moses that the Israelites should live in shelters during the festival to be held that month.

15He had said that a proclamation should be made throughout their towns and in Jerusalem, telling the people to go to the hills to get branches from olive, wild olive, myrtle, palm, and other leafy trees. They were to use these branches to make shelters in which they would live during the festival, as prescribed in the Law.

16So 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.

17So 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.

18Ezra read from the Book of the Law of God on each of the seven days of the festival. Then on the eighth day they held a solemn assembly, as was required by law.
