Nehemiah 12:45-47

45And they kept the charge of their God, and the charge of the purification, and so did the singers and the porters, according to the commandment of David, and of Solomon his son. 46For in the days of David and Asaph of old there was a chief of the singers, and songs of praise and thanksgiving unto God. 47And all Israel in the days of Zerubbabel, and in the days of Nehemiah, gave the portions of the singers and the porters, as every day required: and they set apart that which was for the Levites; and the Levites set apart that which was for the sons of Aaron.
