Now we come to the famous Abraham!
He started out as Abram (Exalted father)
God changed his name to Abraham. (Father of Many)
His wife was born Sarai (Like a Princess)
God changed her name to Sarah (Princess, Queen)
Abraham and Sarah had one son named Isaac
Isaac married Rebekah and has Jacob and Esau.
Abraham also had an Egyptian concubine named Hagar
Hagar gave birth to Ishmael.
Ishmael married an Egyptian woman and had 12 sons who each founded an Arab tribe.
Ishmael also had a daughter who later married Esau.
After Sarah died, Abraham took a 2nd wife named Keturah
(Many people aren't aware of that fact!)
Keturah bore 6 sons, including Jokshan and Midian
Jokshan's descendants lived in Arabia
Midian's descendants settled in Jordan and Sinai and became the ancestors of the Midianites.
One Midianite clan settled in Sinai and became the Kenites
