Generations of Adam

"Generations of Adam" is a concept in Genesis 5:1 in the Hebrew Bible. It is typically taken as the name of Adam's line of descent going through Seth. Another view equates the generations of Adam with material about a second line of descent starting with Cain in Genesis 4, while Genesis 5 is taken as the "generations of Noah".

Both the Cainite and the Sethite lines begin with Adam. The Sethite line in Genesis 5 extends to Noah and his three sons. The Cainite line in Genesis 4 runs to Naamah. The seventh generation Lamech descended from Cain is described as the father of Jabal and Jubal (from his first wife Adah) and Tubal-cain and Naamah (from his second wife, Zillah). The ninth generation Lamech, descended from Seth, is described as the father of Noah. (Gen.4:17-22 Gen.5:1-32).

The Sethite line also gives ages at fatherhood and at death. In the Masoretic text, ages at death range from 777 (Lamech) to 969 (Methuselah), placing the text in the category of longevity narratives. The Septuagint and Samaritan Pentateuch differ somewhat in the ages given; in the Septuagint, the age at fatherhood is often 100 years later than that in the Masoretic text, extending the genealogy by several centuries.

The 2nd-century BC Book of Jubilees, regarded as non-canonical except by the Ethiopian Orthodox Church and the Beta Israel, gives the wives' names for the Sethite line:
