Thought from Today's Old Testament Passage:
[Nehemiah 12 Verses 1-26] 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, Ps. 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 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 v. 1, etc., as eminent in their generation, are again mentioned, though with some variation in several of the names, v. 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.
