Easton's Bible Dictionary (1897)
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.

Her conduct in Egypt, Gen 12:15, and toward Hagar, Gen 16:6; Lev 21:10, and also when Isaac was promised. Gen 18:15, evinced great weakness, but her exemplary faith is commended by the apostles. Heb 11:11; 1 Pet 3:6.
