'Tasks' in the Bible
They performed music before the sanctuary of the meeting tent until Solomon built the Lord's temple in Jerusalem. They carried out their tasks according to regulations.
The rest of their fellow Levites were assigned to perform the remaining tasks at God's sanctuary.
Their relatives, who were leaders of their families, numbered 1,760. They were capable men who were assigned to carry out the various tasks of service in God's temple.
The singers, the heads of the Levite families, stayed in the temple chambers and were exempt from other tasks because they were on duty day and night.
These were the descendants of Levi according to their families, that is, the leaders of families as counted and individually listed who carried out assigned tasks in the Lord's temple and were twenty years old and up.
