'No people' in the Bible

They have angered me with that which is no god; and provoked me with their vanities. And I, again, will anger them with them which are no people, and will provoke them with a foolish nation.

and upon Elam I will bring the four winds from the four quarters of heaven, and will scatter them against the same four winds. And there shall be no people, but some of Elam shall flee unto them.

But I demand whether Israel did know or not? First Moses saith, "I will provoke you for to envy by them that are no people, and by a foolish nation I will anger you."
