 According to the Hebrew Bible narrative , Jewish ancestry is traced back to the Biblical patriarchs such as Abraham , Isaac and Jacob , and the Biblical matriarchs Sarah , Rebecca , Leah , and Rachel , who lived in Canaan around the 18th century BCE . Jacob and his family migrated to Ancient Egypt after being invited to live with Jacob 's son Joseph by the Pharaoh himself . The patriarchs ' descendants were later enslaved until the Exodus led by Moses , traditionally dated to the 13th century BCE , after which the Israelites conquered Canaan .

 The descendants of Abraham and Hagar are called Ishmaelites , after Ishmael , their firstborn , and the Qedarites are named for his second son , Qedar . The Bible refers to both the Qedarites and Qedar frequently . Old Testament references include Genesis ( 25 : 13 ) , Isaiah ( 21 : 16 @-@ 17 , 42 : 11 , 60 : 7 ) , Jeremiah ( 2 : 10 , 49 : 28 @-@ 33 ) , Ezekiel ( 27 : 21 ) , and Chronicles ( 1 : 29 ) . Twice , Qedar is used to refer to the actual son of Ishmael , as in the books of Genesis and Chronicles , while remaining references are to his descendants , referring either to his most prominent North Arabian sons , or to the Arabs and Bedouins as a more general collective . The " tents of Kedar " equated with " the peace @-@ hating Meshech " mentioned in the Book of Psalms ( 120 : 5 ) were likely a Qedarite sub @-@ group .

 Ishmaelism in this more limited definition holds that Ishmael was both an important religious figure and eponymous ancestor for some of the Arabs of western Arabia . Prominence is given in Arab genealogical accounts to the first two of Ishmael 's twelve sons , Nebaioth ( Arabic : نبيت , Nabīt ) and Qedar ( Arabic : قيدار , Qaydār ) , who are also prominently featured in the Genesis account . It is likely that they and their tribes lived in northwestern Arabia and were historically the most important of the twelve Ishamelite tribes .
