Yet the number of the children of Israel will be as the sand of the sea, which can't be measured nor numbered; and it will come to pass that, in the place where it was said to them, 'You are not my people,' they will be called 'sons of the living God.'
And there is an important meaning in the verb, ‘It shall be said:’ It shall be where it had been said, Ye are not my people, there it shall be said, — The Prophet means, that our salvation appears not, before the Lord has begun to testify to us of his good-will. Hence the beginning of our salvation is God’s call, when he declares himself to be propitious to us: without his word, no hope shines on us. Hosea might have said, ‘It shall be in the place where it had been said, Ye are not my people, there they shall begin to be the sons of God:’ but he expresses more, ‘It shall be where it had been said, Ye are not my people, there it shall be said, Ye are the sons of the living God.’
