'Nations' in the Bible

And who is like Your people Israel? God came to one nation on earth in order to redeem a people for Himself, to make a name for Himself, and to perform for them great and awesome acts, driving out nations and their gods before Your people You redeemed for Yourself from Egypt.

King David also dedicated these to the Lord, along with the silver and gold he had dedicated from all the nations he had subdued—

You have freed me from the feuds among my people;You have appointed me the head of nations;a people I had not known serve me.

Therefore I will praise You, Lord, among the nations;I will sing about Your name.
