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.'
Thus then ought this passage, The number of the children of Israel shall be as the sand of the sea, to be expounded: God will gather his Church from all quarters, from the Gentiles as well as from the Jews when the whole world will think it to be extinct.
