Nehemiah 8:13-17

13And on the second day were gathered together the heads of the fathers of all the people, the priests, and the Levites, to Ezra the scribe, even to understand the words of the law.1 14And they found written in the law which the LORD had commanded by Moses, that the children of Israel should dwell in booths in the feast of the seventh month:2 15And that they should declare and proclaim in all their cities, and in Jerusalem, saying, Go forth to the mount, and fetch olive branches, and pine branches, and myrtle branches, and palm branches, and branches of thick trees, to make booths, as it is written. 16So the people went forth, and brought them, and made themselves booths, every one upon the roof of his house, and in their courts, and in the courts of the house of God, and in the street of the water gate, and in the street of the gate of Ephraim. 17And all the congregation of them that had returned from the captivity made booths, and sat under the booths: for since the days of Joshua the son of Nun to that day had not the children of Israel done so. And there was very great gladness.
