'Nations' in the Bible

And what one nation in the earth is like thy people, even like Israel, whom God went to redeem unto himself for a people, and to make him a name, and to do great things for you, and terrible things for thy land, before thy people, whom thou redeemest to thee out of Egypt, from the nations and their gods?

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

Thou also hast delivered me from the strivings of my people; Thou hast kept me to be the head of the nations: A people whom I have not known shall serve me.

Therefore I will give thanks unto thee, O Jehovah, among the nations, And will sing praises unto thy name.
