General Note: The ages above are taken from Genesis 5, 11, and 17–21. Begetting ages and lifespans that match across chronologies are shaded. The begetting age represents when the next successive Patriarch was born (i.e., Adam’s begetting age of 130 indicates that he was 130 when Seth was born).

Note 1: Cainan is not found in the MT or SP genealogies. Cainan is mentioned in most, but not all, manuscripts containing Luke 3:36. Some suppose this to be a scribal error in the transmission of Luke’s Gospel.

Note 2: Shelah is also transliterated as Salah in some English translations.

Note 3: Terah began to have sons when he was 70 (Gen. 11:26). In Genesis 11, the Messianic lineage from Shem to Terah is clearly given, but Terah’s age is only given as 70 when he began to have sons; the common assumption that Terah was 70 when Abram was born is untenable unless he had three sons the same year; rather, Abram was possibly the youngest, which explains why Haran had Lot long before Abram had children and why Acts 7:4 indicates that Abram left Haran after the death of his father. In truth, Terah’s exact age when Abram was born is not indicated; we know only that he had three sons—Abram, Nahor, and Haran—and whomever was the eldest was born when Terah was 70. Abram could have been born when Terah was as young as 70 or as old as 145.
