“But I say, Did not Israel know? First Moses saith, I will provoke you to jealousy by them that are no people, and by a foolish nation I will anger you.”
King James Version (KJV)
10:19 But hath not Israel known - They might have known, even from Moses and Isaiah, that many of the gentiles would be received, and many of the Jews rejected. I will provoke you to jealousy by them that are not a nation - As they followed gods that were not gods, so he accepted in their stead a nation that was not a nation; that is, a nation that was not in covenant with God. A foolish nation - Such are all which know not God. #Deut 32:21|
Ro 10:19-21 Did not Israel know? Why, the Jew is supposed to object, if the Gospel has been extended so widely, is the greater portion of Israel in ignorance that the Gentiles were to be saved? Paul replies that Israel should have known: First, Moses saith. (1) Moses foretells the call of another people to the favor of God (De 32:21); Esaias . . . saith. (2) Isaiah still more plainly predicts the salvation of the Gentiles in Isa 65:1, and (3) he predicts the falling away of Israel in Isa 65:2.
