'Not my people' in the Bible

And He said, Call his name Not-my-people. For you are not My people, and I will not be for you.

Yet the number of the sons of Israel shall be as the sand of the sea, which cannot be measured nor numbered. And it shall be, in the place where it was said to them, You are not My people, there it shall be said to them, You are the sons of the living God.

And I will sow her to Me in the earth. And I will have mercy on No-mercy. And I will say to Not-my-people, You are My people. And they shall say, My God.

As He also says in Hosea, "I will call those not My people, My people; and those not beloved, Beloved."

And it shall be, in the place where it was said to them. "You are not My people; there they shall be called sons of the living God."
