'Not my people' in the Bible

And the Lord said, Give him the name Lo-ammi; for you are not my people, and I will not be your God.

But still the number of the children of Israel will be like the sand of the sea, which may not be measured or numbered; and in place of its being said to them, You are not my people, it will be said to them, You are the sons of the living God

And I will put her as seed in the earth, and I will have mercy on her to whom no mercy was given; and I will say to those who were not my people, You are my people, and they will say, My God.

As he says in Hosea, They will be named my people who were not my people, and she will be loved who was not loved.

And in the place where it was said to them, You are not my people, there they will be named the sons of the living God.
