'Nations' in the Bible

What one nation on earth is like Your people Israel, whom God went to redeem for Himself as a people and to make a name for Himself, and to do great and awesome things for Yourself and for Your land, before Your people whom You have redeemed for Yourself from Egypt, from nations and their gods?

King David also dedicated these [gifts] to the Lord, along with the silver and gold that he had dedicated from all the nations which he subdued:

“You also have rescued me from strife with my [own] people;You have kept me as the head of the nations.People whom I have not known served me.

“For this I will give thanks and praise You, O Lord, among the nations;I will sing praises to Your name.
