In the days of Joiakim, these were the priests who were leaders of the families: of Seraiah, Meraiah; of Jeremiah, Hananiah;

These all served in the days of Joiakim son of Jeshua, the son of Jozadak, and in the days of Nehemiah the governor and of Ezra the priestly scribe. ¹ 

So in the days of Zerubbabel and in the days of Nehemiah, all Israel was contributing the portions for the singers and gatekeepers, according to the daily need. ¹  They also set aside ²  the portion for the Levites, and the Levites set aside the portion for the descendants of Aaron.
