'My People' in the Bible

Many nations shall join themselves to Yahweh in that day, and shall be my people; and I will dwell in the midst of you, and you shall know that Yahweh of Armies has sent me to you.

Thus says Yahweh of Armies: "Behold, I will save my people from the east country, and from the west country;

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

I will bring the third part into the fire, and will refine them as silver is refined, and will test them like gold is tested. They will call on my name, and I will hear them. I will say, 'It is my people;' and they will say, 'Yahweh is my God.'"
