1 Chronicles 5:17

reckoned by genealogy A specimen of this kind of reckoning is given in Nehemiah 7:5-65.

in the days of Jotham … and in the days of Jeroboam "Reckoning by genealogy" is a phrase used only in the writings of the Chronicler (Chron., Ezra, Neh.), but the practice probably resembled what is called in other books "numbering the people." The object however was different and corresponded with the circumstances of the returned exiles, who found themselves in the midst of a Gentile population in Judaea. The people were "reckoned by genealogy" not so much to take a census of them, as to inquire into the purity of their Israelite descent. The ancient term "numbering" would probably be a more suitable description of a transaction belonging to the days of Jotham. For Jothamsee 2 Chronicles 27 and for Jeroboam2 Kings 14:23-29. The last years of the reign of Jeroboam II. synchronized with part at least of the reign of Jotham.
