Nehemiah 8:15-16

15and that they should publish and proclaim through all their cities, and at Jerusalem, saying, Go forth to the mount, and fetch olive-branches, and wild olive-branches, and myrtle-branches, and palm-branches, and branches of thick trees, to make booths, as it is written.

16And the people went forth and brought [them], and made themselves booths, everyone upon the roof of his house, and in their courts, and in the courts of the house of 1God, and in the open space of the water-gate, and in the open space of the gate of Ephraim.
