Nehemiah 8:13

11So the Levites stilled all the people, saying, Hold your peace, for the day is holy; neither be ye grieved.

12And all the people went their way to eat, and to drink, and to send portions, and to make great mirth, because they had understood the words that were declared unto them.

13And on the second day were gathered together the chief of the fathers of all the people, the priests, and the Levites, unto Ezra the scribe, even to understand the words of the law.

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:

15And that they should publish and proclaim in all their cities, and in Jerusalem, saying, Go forth unto 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.
