The leaders of the people all live in Jerusalem, and the people themselves cast lots so that a tenth of them will end up living in Jerusalem. People who offer to go voluntarily (without casting lots) are blessed.
Kind of like when you voluntarily offer to check your carry-on baggage, Virgin America lets you board with Group 1.
Nehemiah lists the Benjaminites and Judahites who lead the province and live in Jerusalem. The leaders of the towns actually live in the towns.
He also lists the leaders of the priests and Levites, and also briefly mentions gatekeepers, singers, and important people like Pethahiah, a guy who helped the king in matters related to the people. Sort of an ombudsman.
Nehemiah concludes with another medium-longish list of all the places and villages where the people lived, including Ono—the valley of the artisans and rumored birthplace of Yoko.
