1 Chronicles 2:9 lists Hezron's three sons — this verse adds a fourth son Ashur born after Hezron's death, continuing the genealogy.

1 Chronicles 4:5 names Ashur of Tekoa and his two wives — directly expanding on the same Ashur introduced in 2:24 as father of Tekoa.

2 Samuel 14:2 tells of a wise woman from Tekoah — the town founded by Ashur in 2:24, linking genealogy to narrative history.

Amos 1:1 identifies the prophet as from Tekoa — the same town founded by Ashur in 2:24, connecting genealogy to prophecy.
