(18) In the book of Moses.--The general arrangements only were given in the Pentateuch. The "courses" were of David's time; and their restoration must have been imperfect, as neither were the twenty-four courses of priests complete nor were the Levites in full force.

Verse 18. - 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of the new temple was naturally followed by an arrangement of the ministers corresponding to that which had been originally made by David, and afterwards adopted by Solomon, for the service of the old temple (see 1 Chronicles 23:6-23; 1 Chronicles 24:1-19).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. CELEBRATION OF THE PASSOVER IN THE ENSUING MONTH, AND OBSERVANCE OF THE FEAST OF UNLEAVENED BREAD (Ezra 6:19-22). Specially solemn passovers were celebrated on specially solemn occasions; and these received special record at the hands of the sacred writers. Of this kind are the passover celebrated By Hezekiah in the year B.C. 726, recorded in 2 Chronicles 30, and that celebrated by Josiah in B.C. 624, recorded in 2 Chronicles 35. Both of these followed upon a cleansing of the temple, and restoration of the temple worship after a period of suspension. Ezra seems to place the passover of B.C. 516 in the same category. It marked the period of the full re-establishment of the regular ordinances of religion, more or less interrupted from the time of the destruction of the temple by Nebuchadnezzar. It terminated the abnormal and commenced the normal condition of things. Perhaps it is to mark this, that Ezra at this point disuses the Chaldee dialect, which he had introduced in ch. 4:8, and returns to the Hebrew, the established language of the Jewish religion.

6:13-22 The gospel church, that spiritual temple, is long in the building, but it will be finished at last, when the mystical body is completed. Every believer is a living temple, building up himself in his most holy faith: much opposition is given to this work by Satan and our own corruptions. We trifle, and proceed in it with many stops and pauses; but He that has begun the good work, will see it performed. Then spirits of just men will be made perfect. By getting their sins taken away, the Jews would free themselves from the sting of their late troubles. Their service was with joy. Let us welcome holy ordinances with joy, and serve the Lord with gladness.And they set the priests in their divisions, and the Levites in their courses, for the service of God which is at Jerusalem,.... All in their proper classes and courses, to do the work of the temple at Jerusalem in their turns:

as it is written in the book of Moses; see Numbers 3:6, from hence it is plain the Pentateuch was not written by Ezra, as suspected by Spinosa (m), but by Moses; see the argument of the book of Genesis. See Gill on Genesis 1:1.
