Deuteronomy 32:21

Ver. 21. I will move them to jealousy with those which are not a people— Nothing can be more glowing and alarming than the terrible denunciations delivered in the subsequent verses against the rebellious and idolatrous Israelites. God threatens to repay their frequent revolts from him in their own coin, in a way most mortifying to their proud spirits, by causing the very Gentile nations whom they so much despised, not only to become their masters and conquerors, but also to be taken into his covenant, while they themselves were excluded from it. See Matthew 21:43.Romans 10:19. We agree with Vitringa, in understanding by those who are not a people, such as were not a people of God in the sense that Israel was; in a word, the barbarous and idolatrous Gentiles, whom the Jews looked upon with the greatest contempt.
