Commentators note that names in this genealogy, like Naaman, are described differently in other parts of the Bible (e.g., as a son of Bela here, but a brother elsewhere). This isn't seen as an error, but as a reflection of how ancient kinship was described. Terms like 'son' could flexibly refer to a grandson or even a descendant leading a clan, showing these lists map tribal relationships, not just a simple family tree.
