The genealogical record returns to the family of Kohath, aiming to expand and provide a deeper account of his descendants [רד״ק]. In this context, references to children broadly indicate later descendants rather than only immediate offspring [ביאור שטיינזלץ].
As the lineage unfolds, a figure named Amminadab is listed among Kohath's descendants. This raises a question about his identity, as he was not mentioned previously among Kohath's direct children. The consensus among commentators is that Amminadab is actually Izhar, a son mentioned earlier in the records, who simply went by two different names.
The family line then continues through his son Korah and proceeds to list Assir. While the phrasing might seem to imply a continuous chain where each person is the son of the one just named, the structure here operates differently. Assir, along with Elkanah and Ebiasaph who follow, do not represent sequential generations. Instead, all three are the direct sons of Korah. This perfectly aligns with earlier records in the Book of Exodus, which explicitly group Assir, Elkanah, and Ebiasaph together as Korah's children [רד״ק, מלבי״ם].
