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.'
You remember Isaiah begins his prophecy, at the beginning of his prophecy, chapter 6, he said, "In the day that king Uzziah died I saw the Lord high and lifted up, sitting on the throne." And then Isaiah does go ahead and has quite a great influence upon Hezekiah.
