Ezra 6:18 - Joseph Benson’s Commentary on the Old and New Testaments

They set the priests in their divisions, &c. When they had dedicated the house, they settled the household: they would have had small comfort in the temple, however solemnly dedicated, without the temple- service: and therefore having set up the worship of God in it, in this dedication of it, they took measures for keeping it up, and in doing so made the book of Moses their rule, to which they had a regard in this establishment. Though the temple-service could not be performed with so much pomp, and such a multitude of sacrifices, and other oblations, as formerly, because of their poverty; yet perhaps it was performed with as much purity, and close adherence to the divine institution, as ever, which was the true glory of it.
