Chapter 23
1-5 (2 Chronicles 8:14). Organization for the Temple Services—[1 Chronicles 23:1-5 quoted.] The four thousand musicians, divided into twenty-four courses, were each lead by twelve men especially instructed and skilful in the use of musical instruments. The work of the porters was also definitely arranged. (3BC 1128.3)
The priests were divided into twenty-four courses, and a full and accurate record was made regarding this division. Each course was thoroughly organized under its chief, and each was to come to Jerusalem twice a year, to attend for one week to the ministry of the sanctuary. (3BC 1128.4)
The Levites, whose duty it was to assist in the sanctuary service, were organized and allotted their part with similar precision (The Review and Herald, October 5, 1905). (3BC 1128.5)
