Contradiction with Nehemiah 7:21
Nehemiah lists the children of Pahath-moab as having different numbers compared to Ezra 2:18.
Nehemiah 7:21: The children of Ater of Hezekiah, ninety and eight.
Paradox #1
The possible issue is a numerical discrepancy between the list of people in Ezra 2 and a similar list in Nehemiah 7. The numbers for some groups differ between the two accounts, which some people see as a contradiction.
