Nehemiah 8:13-15

13On the second day of the month the family leaders met with Ezra the scribe, together with all the people, the priests, and the Levites, to consider the words of the law.

14They discovered written in the law that the lord had commanded through Moses that the Israelites should live in temporary shelters during the festival of the seventh month,

15and that they should make a proclamation and disseminate this message in all their cities and in Jerusalem: “Go to the hill country and bring back olive branches and branches of wild olive trees, myrtle trees, date palms, and other leafy trees to construct temporary shelters, as it is written.”
