1 Chronicles 9:32-34 New Revised Standard Version, Anglicised (NRSVA)
32 Also some of their kindred of the Kohathites had charge of the rows of bread, to prepare them for each sabbath.
33 Now these are the singers, the heads of ancestral houses of the Levites, living in the chambers of the temple free from other service, for they were on duty day and night. 34 These were heads of ancestral houses of the Levites, according to their generations; these leaders lived in Jerusalem.
1 Chronicles 9:32-34 New International Version (NIV)
32 Some of the Kohathites, their fellow Levites, were in charge of preparing for every Sabbath the bread set out on the table.
33 Those who were musicians, heads of Levite families, stayed in the rooms of the temple and were exempt from other duties because they were responsible for the work day and night.
34 All these were heads of Levite families, chiefs as listed in their genealogy, and they lived in Jerusalem.
