Contradiction with 1 Chronicles 9:2
Nehemiah 7:54 refers to the children of Nephishesim among the temple servants, whereas 1 Chronicles 9:2 refers to priests, Levites, and Nethinims but does not mention Nephishesim specifically, suggesting a contradiction in the groups listed in these accounts.
1 Chronicles 9:2: Now the first inhabitants that [dwelt] in their possessions in their cities [were], the Israelites, the priests, Levites, and the Nethinims.
