Wife of Abraham; her striking beauty made Abraham fear the jealousy of powerful men (Gen. 12 and 20). Because of prolonged infertility Sarah persuaded Abraham to beget a child by her maid Hagar, but later Sarah (also called Sarai—both names mean ‘princess’) was promised a son in her old age and Isaac was born. The story of Hagar's use by Abraham and subsequent expulsion with her son Ishmael is given an allegorical interpretation by Paul in Gal. 4: 21–31.
