'Not my people' in the Bible

And he said, "{Name him} Lo-ammi, for you [are] not my people and I am not your [God].

The number of the children of Israel will be like the sand of the sea that cannot be measured or counted; and in the place where it is said to them, "You are not my people," it will be said to them, "Children of [the] living God."

As he also says in Hosea, "I will call those [who were] not my people, 'My people,' and those [who were] not loved, 'Loved.'

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