'Not my people' in the Bible

Then said he, "Call his name Loammi. For why? Ye are not my people, therefore will I not be yours.

And though the number of the children of Israel be as the sand of the sea, which can neither be measured nor told: yet in the place where it is said unto them, 'Ye be not my people': even there shall it be thus reported of them, 'They be the children of the living God.'

I will sow them upon earth, for a seed to mine own self, and will have mercy upon her, that was without mercy. And to them which were not my people, I will say, 'Thou art my people.' And he shall say, 'Thou art my God.'"

As he saith in Hosea, "I will call them my people which were not my people: and her beloved which was not beloved."

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