'Nations of the Earth' in the Bible

Seeing that Abraham shall surely become a great and mighty nation, and all the nations of the earth shall be blessed in him?

And in thy seed shall all the nations of the earth be blessed: because thou hast obeyed my voice.

And I will make thy seed to multiply as the stars of heaven, and will give to thy seed all these countries: and in thy seed shall all the nations of the earth be blessed:

And it shall come to pass, if thou shalt hearken diligently to the voice of the LORD thy God, to observe and to do all his commandments which I command thee this day; that the LORD thy God will set thee on high above all nations of the earth:

Then will I make this house like Shiloh, and will make this city a curse to all the nations of the earth.

And it shall be to me a name of joy, a praise, and an honor before all the nations of the earth, which shall hear all the good that I do to them: and they shall fear and tremble for all the goodness and for all the prosperity that I procure to it.

In that ye provoke me to wrath with the works of your hands, burning incense to other gods in the land of Egypt, whither ye are gone to dwell, that ye may cut yourselves off, and that ye may be a curse and a reproach among all the nations of the earth?
