BBC: Genesis 5:6-20

When Seth had lived 105 years, he fathered Enosh. Seth lived after he fathered Enosh 807 years and had other sons and daughters. Thus all the days of Seth were 912 years, and he died. When Enosh had lived 90 years, he fathered Kenan. Enosh lived after he fathered Kenan 815 years and had other sons and daughters. Thus all the days of Enosh were 905 years, and he died. When Kenan had lived 70 years, he fathered Mahalalel.  Kenan lived after he fathered Mahalalel 840 years and had other sons and daughters. Thus all the days of Kenan were 910 years, and he died. When Mahalalel had lived 65 years, he fathered Jared. Mahalalel lived after he fathered Jared 830 years and had other sons and daughters. Thus all the days of Mahalalel were 895 years, and he died. When Jared had lived 162 years he fathered Enoch. Jared lived after he fathered Enoch 800 years and had other sons and daughters. Thus all the days of Jared were 962 years, and he died. – Genesis 5:6-20

The primary importance of this section of Scripture is the repetitive nature of death. The refrain that would echo the verbal reading of this text would be the conquest of death over the patriarchs (Rom 5:14).
