'Nations' in the Bible

And what one nation on the 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 a great thing for You and awesome things for Your land, before Your people whom You have redeemed for Yourself from Egypt, from nations and their gods?

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

“You have also delivered me from the contentions of my people;You have kept me as head of the nations;A people whom I have not known serve me.

“Therefore I will give thanks to You, O Lord, among the nations,And I will sing praises to Your name.
