Contradiction with 1 Samuel 14:50-51
These verses mention a different genealogy for Saul's family and relatives, which occasionally can highlight differences in tribal associations and roles assigned within Israel that might seem to conflict with Chronicles' detailed genealogical roles but are not directly related to 1 Chronicles 6:45.
1 Samuel 14:50-51: And the name of Saul's wife [was] Ahinoam, the daughter of Ahimaaz: and the name of the captain of his host [was] Abner, the son of Ner, Saul's uncle. [Abner: Heb. Abiner]
