Genealogies of Genesis

The genealogies of Genesis (in chapters 4, 5, and 11 of the Book of Genesis) list the traditional descendants of Adam and Eve to Abraham. Genesis 5 and 11 include the age at which each patriarch had the descendant named in the text and the number of years he lived thereafter. Since Genesis 5 and 11 provide the age of each patriarch at the birth of his named descendant, it presents a gapless chronology from Adam to Abraham, even if the named descendant is not always a first-generation son. That is, a gapless chronology is not dependent on gapless genealogies in Genesis 5 and 11; in fact, an intact chronology is semantically inescapable. Adam's lineage contains two branches: for Cain, given in Chapter 4, and for Seth in Chapter 5. Genesis chapter 10, the Table of Nations records the populating of the Earth by Noah's descendants, and is not strictly a genealogy but an ethnography).

Three versions of the Genesis genealogy exist: the Hebrew Masoretic Text, the Greek Septuagint, and the Hebrew Samaritan Pentateuch. Translations from the Masoretic Text are preferred by Western Christians, including Roman Catholics and Protestants and by followers of Orthodox Judaism, whereas the Greek version is preferred by Eastern Christians, including Eastern Orthodox, Coptic, Ethiopic, Jacobite and Armenian. The Samaritan version of the Pentateuch is used mainly by the Samaritans. The Vulgate, published by Jerome in 405, is a Latin translation based on a Hebrew Tanakh compiled near the end of the first century, whereas the Septuagint was produced during the third century BC based on an earlier version of the Tanakh. Both have, like the Masoretic Text, been the basis for translations into numerous vernacular languages.
