Genesis 25 - 26

Abraham remarries after the death of his wife, Sarah.  More children are born to this patriarch, again fulfilling God's promises to him.  All his wealth, however, is given to his first-born son, Isaac.  Abraham dies at the age of 175.  His two most famous sons, Ishmael and Isaac, continue to see God fulfilling His promises to their father through their own descendants.  Isaac's wife, Rebekah, gives birth to twins named Esau and Jacob.  Esau, by rights the heir, sells his inheritance to his younger brother thinking that a good meal is more to be preferred.  When a famine strikes the land, Isaac attempts to flee to Egypt but God prevents him from doing so.  He travels to the land of the Philistines instead.  He attempts to perpetrate the same lie his father told many years ago in the same land - passing his wife off as his sister.  His lie is soon discovered.  Isaac spends time in the land digging wells, providing water for the area and becoming involved in land disputes when the native inhabitants try to claim the wells as their own.
