'Nations' in the Bible

Who [is] like your people, like Israel? [Israel is] the one nation on earth whose God {led them}, [in order] to redeem a people for himself, and to make a name for himself, and to do for you the great and awesome things for your land in the presence of your people whom he redeemed for himself from Egypt, [from the] nations and their gods.

King David dedicated them also to Yahweh [along] with the silver and the gold that he had dedicated from all of the nations which he had subdued;

You delivered me from the strife of my people; you preserved me as the head of the nations. A people I had not known served me.

Therefore I will extol you, Yahweh, among the nations! I will sing praises to your name!
