Contradiction with Nehemiah 7:63
This verse does not directly contradict Nehemiah 7:20, but covers a different aspect of the genealogical records, focusing on the priests who could not find their ancestry, which is different from the listing of descendants in Nehemiah 7:20.
Nehemiah 7:63: And of the priests: the children of Habaiah, the children of Koz, the children of Barzillai, which took [one] of the daughters of Barzillai the Gileadite to wife, and was called after their name.
