'My People' in the Bible

"Many nations will cling to the LORD at that time and will become my people. I will live in your midst, and you will know that the LORD of the Heavenly Armies has sent me to you.

"This is what the LORD of the Heavenly Armies says: "Look! After having saved my people from the land of the east and from the land of the west,

I will also bring them back to live in the midst of Jerusalem. They will be my people and I will truly be their righteous God.'"

And I will bring that surviving third through, testing them as if through fire, purifying them like silver, assaying them like gold. They will call on my name, and I will answer them. I will say, "This is my people,' and they will say, "The LORD is my God.'"
