Jamieson, Fausset and Brown on Nehemiah 11:4

4. at Jerusalem dwelt certain of the children of Judah--The discrepancy that is apparent between this [Ne 11:4-36] and the list formerly given in 1Ch 9:1-9, arose not only from the Jewish and Oriental practice of changing or modifying the names of persons from a change of circumstances, but from the alterations that must have been produced in the course of time. The catalogue in Chronicles contains those who came with the first detachment of returned exiles, while the list in this passage probably included also those who returned with Ezra and Nehemiah; or it was most probably made out afterwards, when several had died, or some, who had been inserted as going on the journey, remained, and others came in their stead.
