'My People' in the Bible

Thus saith Jehovah of hosts: Behold, I will save my people from the east country and from the west country;

and I will bring them, and they shall dwell in the midst of Jerusalem; and they shall be my people, and I will be their God, in truth and in righteousness.

And I will bring the third part into the fire, and will refine them as silver is refined, and will try them as gold is tried. They shall call on my name, and I will answer them: I will say, It is my people; and they shall say, Jehovah is my God.
