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 years following Creation, 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 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 Yahweh.
