But I say, Did not Israel know? First Moses says,
I will provoke you to jealousy by them that are no people, and by a foolish nation I will anger you.

Paul means here that of course Israel knew…. They all heard but they did not all believe. The jealousy of the Jews arose from their envy at seeing a people which earlier had been without God and barbarous claim the Jewish God as their own and receive the promise which had originally been made to the Jews…. Nothing destroys a man so much as jealousy, which is why God made it the avenger of unbelief, because that is a great sin. Commentary on Paul’s Epistles.
