In Judaism
Sarah first appears in the Book of Genesis, while the Midrash and Aggadah provide some additional commentary on her life and role within Judaism and its ancestral form, Yahwism. She is born Sarai (Hebrew: שָׂרַי) in Ur Kaśdim, or Ur of the Chaldees, believed to have been in present-day Iraq, 1,958 Anno Mundi, according to the Hebrew calendar. She was the daughter of Haran and the granddaughter of Terah, an idolater who worshiped the Moon god Nanna and high-ranking servant of Nimrod, the king of Shinar, or Mesopotamia, but not of his wife, Amathlai. Her name is a feminine form of sar (Hebrew: שַׂר), meaning "chieftain" or "prince". Through Terah, she would have been a 10th-generation descendant of Noah, still alive, living in the Mountains of Ararat, and over nine centuries old at the time of her birth. No details are given as to her life or her religious beliefs before Abraham's return to Ur Kaśdim to thwart Nimrod's efforts to proclaim himself a god. It is known she wed Abraham, then called Abram, sometime between the ages of forty and five and following her husband's public humiliation of Nimrod, she, along with her father Terah, her orphaned nephew Lot, her manservant Eliezer, and some three hundred others left Ur Kaśdim for Canaan, the present-day Levant, to save Abraham from a plot by Nimrod to destroy him, commanded to do so by God.
En route to Canaan, the group stopped in Harran, possibly located in present-day Turkey, settling there for some twenty years, until God urged them to move on and so, they left Terah behind to live out his days, and traveled through Shechem and Bethel, both cities in the present-day West Bank, and, when a famine strikes the region, to Mizraim, present-day Egypt. While in Mizraim, Sarah's beauty attracts the attention of Pharaoh and Abraham, fearing the Egyptians would kill him if they knew Sarah was married to him, introduces himself as her brother and so, Pharaoh bestows upon Abraham great wealth, in the form of livestock and slaves, including Hagar, so that he may take Sarah as his concubine, to live in his palace with him. For Pharaoh's unintentional transgression against Abraham, he and members of his household, save for Sarah, are stricken with plague. Pharaoh then realizes that Abraham is Sarah's husband, not only her brother. Despite Abraham's willful deceit of Pharaoh, Pharaoh does not punish Abraham nor does he require the return of the wealth Abram was given in exchange for Sarah. However, he orders them to leave Mizraim. After leaving Mizraim, Lot splits from their group amicably. He eventually settles in Sodom, over disputes related to the livestock.
They returned to Canaan, and a decade passed and still, she and Abraham had no children. Thus, Sarah offered Hagar, her slavewoman, as a concubine to her husband so that he may have a child. Hagar became pregnant with Ishmael. During Hagar's pregnancy, Sarah and Hagar's relationship deteriorated rapidly, with Sarah striking her and Hagar fleeing into the desert to avoid her, returning only at the urging of angels. God then told Abraham that Sarah would give him a son. Sarah, then ninety years old, laughed at this idea. But, as prophesied, she became pregnant with Isaac and she nursed him herself. She would ultimately demand that Abraham send Hagar and Ishmael away and so, Abraham banished them and sent them into the desert.
Sometime after the birth of Ishmael but before the birth of Isaac, Sarah and Abraham travel to Gerar, as described in Genesis 20, where events took place which mirrored those of Mizraim, in which a king, this time Abimelech, took an interest in Sarah for her beauty and, as he had done in Mizraim, Abraham presented himself as her brother instead of her husband and so, believing her unmarried Abimelech took her into her house as Pharaoh had though, this time, God intervened before he touched Sarah, through dreams and plague. Abimelech confronted Abraham, angry that his lie had caused him to provoke the wrath of a god, but, also like Pharaoh, he bestows great wealth upon Abraham. The two men part amicably, with Abraham saying he will pray for the king, who is childless and without an heir.
Sarah died at the age of 127 years. According to rabbinic tradition in the Midrash, her passing was directly connected to the shock of the Binding of Isaac. Midrashic accounts vary on the exact emotional cause: some state she died from immediate grief upon hearing that her son was about to be sacrificed, others record that Satan intentionally deceived her into believing Isaac had already been slaughtered causing her to die of a broken heart, while a third tradition states that Satan later corrected his report and informed her that Isaac had survived, causing her to die of overwhelming joy upon learning that he was actually alive. She is buried in Kiryat Arba, in Hebron, in the Cave of Machpela.
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. While in Genesis 20:12 Abraham claims that Sarah "is indeed my sister, my father's daughter" rather than his niece, Rashi asserts that the term "daughter" can also be used regarding a granddaughter, and thus "sister" can be used regarding a niece.
The fifth-century rabbinic midrash Genesis Rabbah dedicates a large amount of attention to Sarah in particular. Not only are a relatively large number of drashot dedicated to the matriarch, but she is repeatedly depicted as a model of personal and religious excellence. This is marked break from the biblical and Second Temple literature in which she plays a far more ancillary role. In light of parallels between the rabbis' characterization of Sarah and early Christian themes connected to the Virgin Mary popular in this same period, it has been suggested that the rabbis used their portrayal of Sarah to establish her as a Jewish alternative to the Virgin Mary.
When brought before Pharaoh, Sarah said that Abram was her brother, and the king thereupon bestowed upon the latter many presents and marks of distinction. As a token of his love for Sarai the king deeded his entire property to her, and gave her the land of Goshen as her hereditary possession: for this reason the Israelites subsequently lived in that land. Sarai prayed to God to deliver her from the king, and He thereupon sent an angel, who struck Pharaoh whenever he attempted to touch her. Pharaoh was so astonished at these blows that he spoke kindly to Sarai, who confessed that she was Abraham's wife. The king then ceased to annoy her. According to another version, Pharaoh persisted in annoying her after she had told him that she was a married woman; thereupon the angel struck him so violently that he became ill, and was thereby prevented from continuing to trouble her. According to one tradition it was when Pharaoh saw these miracles wrought in Sarai's behalf that he gave her his daughter Hagar as slave, saying: "It is better that my daughter should be a slave in the house of such a woman than mistress in another house." Abimelech acted likewise. In Genesis 17:15, God changes her name to Sarah (princess) ("a woman of high rank") as part of the covenant with El Shaddai after Hagar bears Abram his first born son Ishmael.
Sarai treated Hagar well, and induced women who came to visit her to visit Hagar also. Hagar, when pregnant by Abraham, began to act superciliously toward Sarai, provoking the latter to treat her harshly, to impose heavy work upon her, and even to strike her. Some believe Sarai was originally destined to reach the age of 175 years, but forty-eight years of this span of life were taken away from her because she complained of Abraham, blaming him as though he was the cause that Hagar no longer respected her. Sarah was sterile; but a miracle was granted to her after her name was changed from "Sarai" to "Sarah". According to one myth, when her fertility had been restored and she had given birth to Isaac, the people would not believe in the miracle, saying that the patriarch and his wife had adopted a foundling and pretended that it was their own son. Abraham thereupon invited all the notabilities to a banquet on the day when Isaac was to be weaned. Sarah invited the women, also, who brought their infants with them; and on this occasion she gave milk from her breasts to all the strange children, thus convincing the guests of the miracle.
Legends connect Sarah's death with the attempted sacrifice of Isaac, however, there are two versions of the story. According to one, Samael came to her and said: "Your old husband seized the boy and sacrificed him. The boy wailed and wept; but he could not escape from his father." Sarah began to cry bitterly, and ultimately died of her grief. According to the other legend, Satan came to Sarah disguised as an old man, and told her that Isaac had been sacrificed. Believing it to be true, she cried bitterly, but soon comforted herself with the thought that the sacrifice had been offered at the command of God. She started from Beer-sheba to Hebron, asking everyone she met if he knew in which direction Abraham had gone. Then Satan came again in human shape and told her that it was not true that Isaac had been sacrificed, but that he was living and would soon return with his father. Sarah, on hearing this, died of joy at Hebron. Abraham and Isaac returned to their home at Beer-sheba, and, not finding Sarah there, went to Hebron, where they discovered her dead. According to the Genesis Rabbah, during Sarah's lifetime her house was always hospitably open, the dough was miraculously increased, a light burned from Friday evening to Saturday evening, and a pillar of cloud rested upon the entrance to her tent.
