'Nations' in the Bible

What one nation in the earth is like your people, even like Israel, whom God went to redeem to himself for a people, and to make him a name, and to do great things for you, and awesome things for your land, before your people, whom you redeem to you out of Egypt, [from] the nations and their gods?

These also did king David dedicate to Yahweh, with the silver and gold that he dedicated of all the nations which he subdued;

You also have delivered me from the strivings of my people. You have kept me to be the head of the nations. A people whom I have not known will serve me.

Therefore I will give thanks to you, Yahweh, among the nations. Will sing praises to your name.
