(2004/5765) Parshat Chayei Sarah opens with the Pasuk,
“Sarah’s lifetime was one hundred years, twenty years, and
seven years; the years of Sarah’s life.”
Why does the Pasuk have to repeat the word years?
Rashi says that the word is repeated because Sarah’s life
was divided into three separate periods. At age one hundred,
she was as sinless as she was at twenty, as a person does
not suffer heavenly punishment at the age of twenty. At the
age of twenty, she still had the wholesome beauty as a seven
year old, whose beauty is natural.
R’ Moshe Feinstein commented here that, despite
Sarah’s breathtaking beauty, everyone that saw her
recognized her purity and innocence.
