Nehemiah 8:16

So the people went forth, and brought them
Went out of Jerusalem to the mountains adjacent, and fetched in branches of the said trees, one or another:

and made themselves booths, everyone upon the roof of his house;
which were flat, ( Deuteronomy 22:8 ) , and they might be made anywhere, so be it they were open to the air:

and in their courts, and in the courts of the house of God;
the common people in the courtyards belonging to their houses, and the priests and Levites in the courts of the temple, the yards or open places adjoining to them:

and in the street of the watergate;
which led to that, and seems to have been a very large street, in which many booths might be built, ( Nehemiah 3:26 ) ( 8:3 )

and in the street of the gate of Ephraim;
which led to the gate through which the road lay to the tribe of Ephraim, see ( 2 Kings 14:13 ) , none were erected without the walls of the city, for fear of the enemy.
