Ezra 6:18 - Exposition

They set the priests in their divisions, and the Levites in their courses. The completion of the new temple was naturally followed by an arrangement of the ministers corresponding to that which had been originally made by David, and afterwards adopted by Solomon, for the service of the old temple (see 1 Chronicles 23:6-23 ; 1 Chronicles 24:1-19 ). This arrangement was based upon the ordinances of the law with respect to the respective offices of the two orders, as given in the Book of Numbers ( Numbers 3:6-10 ; Numbers 8:6-26 ), and, so far, was according to the writing of the book of Moses. But the "courses" themselves were not established till David's time.
