The lifespans recorded for the generations of this era follow a precise, underlying mathematical pattern. For three consecutive generations, the ages are built upon a fixed foundation of exactly two hundred years. Any additional time lived is simply added to this shared base number.
When looking at the remaining years of Peleg's life after the birth of his son, the total comes to two hundred and nine years. This is the standard base of two hundred, with an extra nine years added on. The same structural logic applies to his entire lifespan, which totals two hundred and thirty-nine years. This final number is calculated by taking the foundational two hundred years and adding exactly thirty-six years, along with another thirty-six months [קאסוטו].
