Romans 10:19-20

19But I say, did Israel fail to understand [that the gospel was to go also to the Gentiles]? First Moses says, “I will make you jealous of those who are not a nation (Gentiles); With a nation that lacks understanding I will make you angry.”

20Then Isaiah is very bold and says, “I have been found by those who did not seek Me; I have shown Myself to those who did not [consciously] ask for Me.”
