'Not my people' in the Bible

Then said God, Call his name Loammi: for ye 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, Ye are not my people, there it shall be said unto them, Ye are the sons of the living God.

And I will sow her unto me in the earth; and I will have mercy upon her that had not obtained mercy; and I will say to them which were not my people, Thou art my people; and they shall say, Thou art my God.

As he saith also in Osee, I will call them my people, which were not my people; and her beloved, which was not beloved.

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