We have here the names, and little more than the names, of a great many priests and Levites, that were eminent in their day among the returned Jews. Why this register should be here inserted by Nehemiah does not appear, perhaps to keep in remembrance those good men, that posterity might know to whom they were beholden, under God, for the happy revival and re-establishment of their religion among them. Thus must we contribute towards the performance of that promise, Psa 112:6, The righteous shall be in everlasting remembrance. Let the memory of the just be blessed, be perpetuated. It is a debt we still owe to faithful ministers to remember our guides, who have spoken to us the word of God, Heb 13:7. Perhaps it is intended to stir up their posterity, who succeeded them in the priest's office and inherited their dignities and preferments, to imitate their courage and fidelity. It is good to know what our godly ancestors and predecessors were, that we may learn thereby what we should be. We have here, 1. The names of the priests and Levites that came up with the first out of Babylon, when Jeshua was high priest. Jeremiah and Ezra are mentioned with the first (Neh 12:1), but, it is supposed, not Jeremiah the prophet nor Ezra the scribe; the fame of the one was long before and that of the other some time after, though both of them were priests. Of one of the Levites it is said (Neh 12:8) that he was over the thanksgiving, that is, he was entrusted to see that the psalms, the thanksgiving psalms, were constantly sung in the temple in due time and manner. The Levites kept their turns in their watches, reliving one another as becomes brethren, fellow-labourers, and fellow-soldiers. 2. The succession of high priests during the Persian monarchy, from Jeshua (or Jesus), who was high priest at the time of the restoration, to Jaddua (or Jaddus), who was high priest when Alexander the Great, after the conquest of Tyre, came to Jerusalem, and paid great respect to this Jaddus, who met him in his pontifical habit, and showed him the prophecy of Daniel, which foretold his conquests. 3. The next generation of priests, who were chief men, and active in the days of Joiakim, sons of the first set. Note, We have reason to acknowledge God's favour to his church, and care of it, in that, as one generation of ministers passes away, another comes. All those who are mentioned Neh 12:1, etc., as eminent in their generation, are again mentioned, though with some variation in several of the names, Neh 12:12, etc., except two, as having sons that were likewise eminent in their generation - a rare instance, that twenty good fathers should leave behind them twenty good sons (for so many here are) that filled up their places. 4. The next generation of Levites, or rather a latter generation; for those priests who are mentioned flourished in the days of Joiakim the high priest, these Levites in the days of Eliashib, Neh 12:22. Perhaps then the forementioned families of the priests began to degenerate, and the third generation of them came short of the first two; but the work of God shall never fail for want of instruments. Then a generation of Levites was raised up, who were recorded chief of the fathers (Neh 12:22), and were eminently serviceable to the interests of the church, and their service not the less acceptable either to God or to his people for their being Levites only, of the lower rank of ministers. Eliashib the high priest being allied to Tobiah (Neh 13:4), the other priests grew remiss; but then the Levites appeared the more zealous, as appears by this, that those who were now employed in expounding (Neh 8:7) and in praying (Neh 9:4, Neh 9:5) were all Levites, not priests, regard being had to their personal qualifications more than to their order. These Levites were some of them singers (Neh 12:24), to praise and give thanks, others of them porters (Neh 12:25), keeping the ward at the thresholds of the gates, and both according to the command of David.

The thresholds of the gates - Some understand this of a sort of porticoes at the gates, and are puzzled about it, because they find no mention of porticoes elsewhere: but why may we not suppose these to resemble our watch-boxes or some temporary moveable shelters for those who took care of the gates? That there must have been some such conveniences, common sense dictates.

These were in the days of Joiakim the son of Jeshua, the son of Jozadak,.... Who was high priest in Babylon, and whose grandson was now high priest in the time referred to:

and in the days of Nehemiah the governor; the writer of this book:

and of Ezra the priest, the scribe; who was contemporary with him.

The sons of Levi . . . were written in the book of the chronicles--that is, the public registers in which the genealogies were kept with great regularity and exactness.
