'My People' in the Bible

And many nations shall be joined to the LORD in that day, and shall be my people: and I will dwell in the midst of you, and you shall know that the LORD of hosts has sent me unto you.

Thus says the LORD 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 through the fire, and will refine them as silver is refined, and will test them as gold is tested: they shall call on my name, and I will hear them: I will say, They are my people: and they shall say, The LORD is my God.
