This seems to be more historical, introducing Abram (a.k.a. Abraham) and setting the stage for things to come, than a story with specific meaning.  Abram obeys God by moving to Canaan, modern day Israel, and is told he will be given “many descendants, and they will become a great nation”.

But, then famine hits and they all move to Egypt where Abram deceives the King into buying his wife Sarai (a.k.a. Sarah) as his sister.  The King receives terrible diseases from God, likely carried by Sarai, on him and the people of his palace, so he kicks Abram’s clan out of Egypt.  Abram returns to Canaan rich.

Abram doesn’t seem like the noblest father to the 3.6 billion Christians, Muslims, and Jewish people of today (see Wiki Number of Followers chart) in this story.
