32:21 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 {n} people; I will provoke them to anger with a foolish nation.
(n) Which I have not favoured, nor given my law to them.
32:21 I will move them to jealousy with those that are not a people - With the Heathen nations, who are none of my people, who scarce deserve the name of a people, as being without the knowledge and fear of God, which is the foundation of all true policy and government, and many of them destitute of all government, laws and order. And yet these people I will take in your stead, receive them and reject you; which, when it came to pass how desperately did it provoke the Jews to jealousy? 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, there being nothing more foolish or brutish than the worship of idols.
32:19-25 The revolt of Israel was described in the foregoing verses, and here follow the resolves of Divine justice as to them. We deceive ourselves, if we think that God will be mocked by a faithless people. Sin makes us hateful in the sight of the holy God. See what mischief sin does, and reckon those to be fools that mock at it.
