As for Elkanah: the sons of Elkanah; Zophai his son, and Nahath his son,
1 Chronicles 6:26 belongs to the genealogical records in Chronicles, standing within 1 Chronicles 5-7 which record names and family lines among the tribes. Within those records it belongs to the genealogy of Levi, reflecting the particular attention given to Judah and the priesthood. It records Elkanah's place in the genealogy, naming Zophai and Nahath among his ancestors.
These records preserved the records of God's people and the integrity of the tribes, showing that God was particular in preserving family lines. After the exile they provided proof of hereditary descent needed for assigning land and maintaining temple service. The priestly line thus preserved continued until Christ's priesthood superseded it.
