Nehemiah 8:13-17

13On the second day of the month, the heads of all the families, along with the priests and the Levites, gathered around Ezra the teacher to give attention to the words of the Law. 14They found written in the Law, which the LORD had commanded through Moses, that the Israelites were to live in temporary shelters during the festival of the seventh month

15and that they should proclaim this word and spread it throughout their towns and in Jerusalem: “Go out into the hill country and bring back branches from olive and wild olive trees, and from myrtles, palms and shade trees, to make temporary shelters”—as it is written. See Lev. 23:37-40. 16So the people went out and brought back branches and built themselves temporary shelters on their own roofs, in their courtyards, in the courts of the house of God and in the square by the Water Gate and the one by the Gate of Ephraim.

17The whole company that had returned from exile built temporary shelters and lived in them. From the days of Joshua son of Nun until that day, the Israelites had not celebrated it like this. And their joy was very great.
