'Not my people' in the Bible

Then the Lord said: "Name him 'Not My People' (Lo-Ammi), because you are not my people and I am not your God."

However, in the future the number of the people of Israel will be like the sand of the sea which can be neither measured nor numbered. Although it was said to them, "You are not my people," it will be said to them, "You are children of the living God!"

Then I will plant her as my own in the land. I will have pity on 'No Pity' (Lo-Ruhamah). I will say to 'Not My People' (Lo-Ammi), 'You are my people!' And he will say, 'You are my God!'"

As he also says in Hosea: "I will call those who were not my people, 'My people,' and I will call her who was unloved, 'My beloved.'"

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