'Not my people' in the Bible

Then said God, Call his name Loammi: for you are not my people, and I will not be your God.

Yet the number of the children of Israel shall be as the sand of the sea, which cannot be measured nor numbered; and it shall come to pass, that in the place where it was said unto them, you are not my people, there it shall be said unto them, you are the sons of the living God.

And I will sow her for myself in the earth; and I will have mercy upon her that had not obtained mercy; and I will say to them who were not my people, you are my people; and they shall say, you are my God.

As he says also in Hosea, I will call them my people, who were not my people; and her beloved, who was not beloved.

And it shall come to pass, that in the place where it was said unto them, You are not my people; there shall they be called the children of the living God.
