Sarah, originally called Sarai, was Abraham’s wife and the mother of Isaac, the child of promise. Her life is closely linked with the covenant family, and the New Testament presents her as an example of faith.
Definition
Sarah, originally Sarai, was Abraham’s wife and half-sister and the mother of the promised child. Her life is closely joined to Abraham’s history. She died at the age of 127, and her death led Abraham to purchase the cave of Machpelah as a family burial place.
Biblical Usage
Sarah is associated with the promised child and the covenant family. Paul uses her allegorically as a type of the Jerusalem above, and Hebrews names her among those who died in faith.
Historical Background
Sarah is the biblical form of the name whose meaning is “princess.” Scripture uniquely records the age of a woman at her death in Sarah’s case.

Easton's Bible Dictionary
Princess, the wife and at the same time the half-sister of Abraham (Gen. 11:29; 20:12). This name was given to her at the time that it was announced to Abraham that she should be the mother of the promised child. Her story is from her marriage identified with that of the patriarch till the time of her death. Her death, at the age of one hundred and twenty-seven years (the only instance in Scripture where the age of a woman is recorded), was the occasion of Abraham’s purchasing the cave of Machpelah as a family burying-place. In the allegory of Gal. 4:22-31 she is the type of the “Jerusalem which is above.” She is also mentioned as Sara in Heb. 11:11 among the Old Testament worthies, who “all died in faith.” (See ABRAHAM.)
