Easton's 1897 Bible Dictionary
Sarah
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}.)
