Nehemiah 8:13-15

13And on the second day were gathered together the heads of fathers’housesof all the people, the priests, and the Levites, unto Ezra the scribe, even to give attention to the words of the law. 14And they found written in the law, how that Jehovah 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 branches of wild olive, and myrtle branches, and palm branches, and branches of thick trees, to make booths, as it is written.
