The roof. The flat roofs of Oriental houses and the courts round which they were commonly built furnished convenient sites for the booths, and could be used by the inhabitants of Jerusalem. Visitors from the country (see verse 15) occupied the open spaces in the city and the Temple courts, where many could be accommodated.
Water gate. See verse 1 and on Nehemiah 3:26.
The gate of Ephraim. This gate lay between the Broad Wall and the so-called Old Gate, according to Nehemiah 12:38, 39, and must therefore have been in the western wall. That it is not mentioned in the list of Nehemiah 3 may be due either to a gap in the list somewhere in Nehemiah 3:6-8 or to the fact that this particular gate had been completed prior to Nehemiah’s arrival. If it had not been burned by enemies attacking the city (see Nehemiah 1:3), it would not be in need of repair.
