With those which are not a people, i.e. with the Gentile or heathenish nations, who are none of my people, who scarce deserve the name of a people, as being without yoke, without the knowledge and fear of God, which is the foundation of all true policy and government, and without righteous and necessary laws; and many of them are destitute of all government, and laws, and order, barbarous and rude, and savage, and brutish in their manners. And yet these people I will prefer before you, and take in your stead; receive them, and reject you; which, when it came to pass, how desperately it provoked the Jews to jealousy, may be gathered from Matthew 21:43 Acts 11:2,3 Acts 22:21-23 1 Thessalonians 2:15,16. A foolish nation; so the Gentiles were both in the opinion of the Jews, and in truth and reality, notwithstanding all their pretences to wisdom, Romans 1:22, there being nothing more foolish or brutish than the worship of idols. See Jeremiah 10:8 1 Corinthians 12:2.

21 They have moved me to jealousy with that which is not God; they have provoked me to anger with their vanities: and I will move them to jealousy with those which are not a people; I will provoke them to anger with a foolish nation.
