'Nations' in the Bible

These King David made holy to the Lord, together with the silver and gold which he had taken from the nations he had overcome--

The nations of Edom and Moab, and the children of Ammon and the Philistines and the Amalekites and the goods he had taken from Hadadezer, the son of Rehob, king of Zobah.

You have made me free from the fightings of my people; you have made me the head of the nations: a people of whom I had no knowledge will be my servants.

Because of this I will give you praise, O Lord, among the nations, and will make a song of praise to your name.
