בראשית, פרק י״א, פסוק כ״ה

During this era of history, there is a steady decline in human lifespan, and the life of Nahor marks the absolute lowest point of this downward trend. He rushes to bring children into the world and hurries to leave it, living a total of only 148 years. To put this rapid decline into perspective, his ancestor Shem lived for 600 years—a complete unit of time known as a ner. Nahor, by contrast, does not survive for even a quarter of that duration. The 119 years he lives after the birth of his son amount to two sixty-year cycles, falling short by just one year.

However, this sharp drop in human longevity halts with the next generation. Terah, the son of Nahor, rebounds from this low point and lives significantly longer than his father. This sudden extension of life is granted to Terah because he is destined to father a figure of immense importance—Abraham [קאסוטו].
