God created the world, and after it human beings.
Adam was the first man.
The descendants of Adam and Eve led to Noah, who had a son named Shem from which the word Semite derives.
The descendants of Shem led to Abraham who married Sarah.
Sarah had no son for long time.
Abraham and Sarah turned very old without any child.
So Abraham took Hagar for his second wife.
Hagar bore him a son, Ishmael.
Sarah then demanded that Abraham banish Ishmael and Hagar from the tribe.
Abraham took them to Macca.
Then, Sarah bore Isaac.
