This verse, part of a larger genealogy, establishes the direct lineage leading to Moses and Aaron through their grandfather, Kohath. Commentators like John Gill highlight that these specific details, including names and lifespans, are not just filler. They serve to ground the story of redemption in real history, showing God working through a specific family line. The accuracy of these details is even noted by ancient non-biblical historians, reinforcing the reliability of the biblical account.
