The Story of Abraham :

Abraham migrated with his father Terah from Ur to Haran. After his father's death God called Abraham to go to the land that he would show him where he would make of Abraham a great nation.  Abraham went to Canaan with his wife  Sarah and nephew Lot.  As Abraham and Sarah grew older they had no children, so Abraham fathered a son, Ishmael, through Sarah's servant Hagar. The birth of Ishmael did not fulfill God's promise of a child to Abraham and Sarah so the promise of a great nation remained unrealized.  God reaffirmed his promise to give Abraham descendants and God made circumcision the sign of his covenant relationship. When Abraham was 100 years old, Sarah bore a son named Isaac.  God tested Abraham by commanding him to sacrifice Isaac. As they traveled, Isaac asked what they would sacrifice and Abraham replied that God would provide the lamb. As Abraham made ready to sacrifice the boy, God intervened and spared him, and Abraham sacrificed a ram caught in the bushes.

The Story of Isaac & Jacob:

Jacob was one of the twin sons of Issac. He went on to become the father of the 12 tribes of Israel.
