Nehemiah 8:15-16

15So that they should proclaim and spread this message in all their towns and in Jerusalem saying, “Go out to the hill country and bring olive branches and wild olive branches, myrtle branches, palm branches and branches of other leafy trees to make sukkot, just as it is written.”

16So the people went out and brought branches, and made sukkot for themselves, each on their own roof, in their courtyards, in the courtyards of the House of God, in the plaza before the Water Gate and in the plaza of the Ephraim Gate.
