So in the days of Zerubbabel and of Nehemiah, all the Israelites gave every day to support the singers and gatekeepers. The people also set aside the money for the other Levites. And the Levites set aside the money for the descendants of Aaron.
The Levites who were singers and leaders of their families stayed in the rooms at the Temple. They did not have to do other work because they were responsible for the work in the Temple day and night.
