And 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.
And these are the singers, heads of fathers’ houses of the Levites, who dwelt in the chambers and were free from other service; for they were employed in their work day and night.
