Genesis 23:1

“And Sarah was an hundred and seven and twenty years old, etc.] This following immediately upon the account of the offering up of Isaac, led many of the Jewish writers to conclude, that Isaac was when thirty seven years of age, as he must be when Sarah his mother was one hundred and twenty seven, for he was born when she was ninety years of age; but this seems not to be observed on that account, but to give the sum of her age at her death, since it follows: [these were] the years of the life of Sarah; who, as it is remarked by many interpreters, is the only woman the years of whose life are reckoned up in Scripture.”

“AGE AND DEATH OF SARAH. (Gen 23:1-2) Sarah was an hundred and seven and twenty years old, &c.--Sarah is the only woman in Scripture whose age, death, and burial are mentioned, probably to do honor to the venerable mother of the Hebrew people.”

“23:1-20 When Sarah . . . died, Abraham acquired a parcel of land for a burial place. This transaction was the first sign that a permanent transition had taken place, as people were normally buried in their ancestral homeland (cp. 49:29–50:13). In burying Sarah, Abraham detached from his just-mentioned ancestral home (where his relatives still lived, 22:20-24); his future would be in Canaan, where his descendants would realize the promise. 23:1-2 Sarah was 127 years old: Isaac was 37 at this time (cp. 17:17). • Hebron: See study note on 13:18.”
