Nehemiah 8:15-18

and that they should publish and proclaim in all their cities, and in Jerusalem, saying, Go forth unto the mount, and fetch olive branches, and branches of wild olive, and myrtle branches, and palm branches, and branches of thick trees, to make booths, as it is written. So 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 broad place of the water gate, and in the broad place of the gate of Ephraim. And all the assembly of them that were come again out of the captivity made booths, and dwelt in the booths: for since the days of Jeshua the son of Nun unto that day had not the children of Israel done so. And there was very great gladness. Also day by day, from the first day unto the last day, he read in the book of the law of God. And they kept the feast seven days; and on the eighth day was a solemn assembly, according unto the ordinance.
