11:27 generations of Terah. This statement seems to conclude Terah’s tablet, which thus consisted solely of the genealogical records from Shem to himself (Genesis 11:10-27). If there are no gaps in the genealogies, Shem lived until after Terah’s death, so Terah could easily have gotten the earlier tablets from Shem. Likewise, he could easily have transmitted them later to Abraham, or even to Isaac, since he lived until Isaac was thirty-five years old (see Genesis 11:26,32; 21:5), assuming Abram was his oldest son.
11:27 Terah begat Abram. Isaac is apparently the author of the next toledoth, and he seems to have keyed his record back into Terah’s simply by repeating the conclusion of the latter.
11:27 Haran. The names of both Nahor (named after his grandfather) and Haran are associated with cities in Mesopotamia (Genesis 24:10; 28:10). Haran died when relatively young, evidently while visiting his father back in Ur (Genesis 11:26 28,32). His son, Lot, soon became attached to his Uncle Abram.
