Genesis 23:1 - Exposition

And Sarah was an hundred and seven and twenty years old (literally, and the lives of Sarah were an hundred and twenty and seven years ); so that Isaac must have been thirty-seven, having been born in his mother's ninetieth year. Sarah, as the wife of Abraham and the mother of believers ( Isaiah 51:2 ; 1 Peter 3:6 ), is the only woman whose age is mentioned in Scripture. These were the years of the life of Sarah —an emphatic repetition designed to impress the Israelitish mind with the importance of remembering the age of their ancestress.
