Son of Serug, father of Terach, grandfather of Avraham
Lived 148 years (Genesis 11:24–25) — a sharp drop from the lifespans of his ancestors, marking the narrowing approach toward Avraham's generation
“Grandfather of Avraham — not to be confused with Avraham's brother of the same name”
Traditional note: DISAMBIGUATION: This Nachor (son of Serug, father of Terach, Genesis 11:22–25) is a different person from the better-known Nachor who is Terach's son and Avraham's brother (Genesis 11:26–27), grandfather of Rivkah through Betuel (Genesis 22:20–23, 24:15). The two share a name three generations apart, a recurring pattern in this genealogy (compare the two Lemechs and the two Cainans/Kenans noted elsewhere in this dataset). This entry's id, 'nachor-ben-serug', is chosen specifically to avoid future collision with Avraham's brother, should that figure be added via the Rivkah/Betuel/Lavan line.
