'Nations' in the Bible

As it is written, "I have made you the father of many nations." Abraham acted in faith when he stood in the presence of God, who gives life to the dead and calls into existence things that don't yet exist.

Hoping in spite of hopeless circumstances, he believed that he would become "the father of many nations," just as he had been told: "This is how many descendants you will have."

And again, "Praise the Lord, all you gentiles! Let all the nations praise him."
