Genesis 11:10-32
The Babel-builders said na'aseh-lanu shem — let us make for ourselves a name. Eight verses later the text answers them with a different shem entirely: eleh toledot Shem — these are the generations of Shem. The line through which the name-promise will travel is literally called Name. Ten generations descend from that line, then narrow into the toledot of Terah and stop in Ur Kasdim with a barren wife, an idol-serving father, and a brother dead in the family's birth-land. Out of those three impossibilities YHWH calls one man into a moledet he must leave for a patris he must seek.
Genesis 5:1-32
Genesis 5 is the chapter where the fall's vocabulary becomes a family vocabulary. Ten generations descend under a metronomic formula — lived, fathered, lived more, died — until the formula breaks twice: at Enoch, who does not die, and at Lamech, who names his son Noah using the same word God used for the pain of the curse eight generations earlier.
Genesis 5, 11
The Masoretic Text's genealogical numbers place Noah's death when Abraham was 58 years old. The Septuagint's numbers put 722 years between them. Both can't be right.
