Sarah in Rabbinic Literature - in The Hebrew Bible

In The Hebrew Bible

Sarah was the wife of Abraham, as well as being his half-sister, the daughter of his father Terah. Sarah was ten years younger than her husband. The Talmud identifies Sarai with Iscah, daughter of Abraham's deceased brother Haran, so that in this Sarah turns out to be the niece of Abraham and the sister of Lot and Milcah. She was also the mother-in-law of Rebecca. She was considered beautiful to the point that Abraham feared that when they were near more powerful rulers she would be taken away and given to another man. Twice he purposefully identified her as being only his sister so that he would be "treated well" for her sake. It is apparent that she remained attractive into her later years, but was barren for an unknown reason. She was originally called "Sarai" which is translated "my princess." Later she was called "Sarah" i.e., princess." In Biblical times, the changing of one's name was significant and used to symbolize the binding of a covenant. In this case, God promised to put an end to her barrenness and give her a child (Isaac).
