19 "The Lord saw this and drew back, provoked to anger by his own sons and daughters. 20 He said, 'I will abandon them; then see what becomes of them. For they are a twisted generation, children without integrity. 21 They have roused my jealousy by worshiping things that are not God; they have provoked my anger with their useless idols. Now I will rouse their jealousy through people who are not even a people; I will provoke their anger through the foolish Gentiles. 22 For my anger blazes forth like fire and burns to the depths of the grave. It devours the earth and all its crops and ignites the foundations of the mountains. 23 I will heap disasters upon them and shoot them down with my arrows. 24 I will weaken them with famine, burning fever, and deadly disease. I will send the fangs of wild beasts and poisonous snakes that glide in the dust. 25 Outside, the sword will bring death, and inside, terror will strike both young men and young women, both infants and the aged.

Commentary on Deuteronomy 32:19-25

(Read Deuteronomy 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.
