26 I would have annihilated them, wiping out even the memory of them. 27 But I feared the taunt of Israel's enemy, who might misunderstand and say, "Our own power has triumphed! The Lord had nothing to do with this!"' 28 "But Israel is a senseless nation; the people are foolish, without understanding. 29 Oh, that they were wise and could understand this! Oh, that they might know their fate! 30 How could one person chase a thousand of them, and two people put ten thousand to flight, unless their Rock had sold them, unless the Lord had given them up? 31 But the rock of our enemies is not like our Rock, as even they recognize. 32 Their vine grows from the vine of Sodom, from the vineyards of Gomorrah. Their grapes are poison, and their clusters are bitter. 33 Their wine is the venom of serpents, the deadly poison of cobras. 34 "The Lord says, 'Am I not storing up these things, sealing them away in my treasury? 35 I will take revenge; I will pay them back. In due time their feet will slip. Their day of disaster will arrive, and their destiny will overtake them.' 36 "Indeed, the Lord will give justice to his people, and he will change his mind about his servants, when he sees their strength is gone and no one is left, slave or free. 37 Then he will ask, 'Where are their gods, the rocks they fled to for refuge? 38 Where now are those gods, who ate the fat of their sacrifices and drank the wine of their offerings? Let those gods arise and help you! Let them provide you with shelter!

Commentary on Deuteronomy 32:26-38

(Read Deuteronomy 32:26-38)

The idolatry and rebellions of Israel deserved, and the justice of God seemed to demand, that they should be rooted out. But He spared Israel, and continues them still to be living witnesses of the truth of the Bible, and to silence unbelievers. They are preserved for wise and holy purposes and the prophecies give us some idea what those purposes are. The Lord will never disgrace the throne of his glory. It is great wisdom, and will help much to the return of sinners to God, seriously to consider their latter end, or the future state. It is here meant particularly of what God foretold by Moses, about this people in the latter days; but it may be applied generally. Oh that men would consider the happiness they will lose, and the misery they will certainly plunge into, if they go on in their trespasses! What will be in the end thereof? Jeremiah 5:31. For the Lord will in due time bring down the enemies of the church, in displeasure against their wickedness. When sinners deem themselves most secure, they suddenly fall into destruction. And God's time to appear for the deliverance of his people, is when things are at the worst with them. But those who trust to any rock but God, will find it fail them when they most need it. The rejection of the Messiah by the Jewish nation, is the continuance of their ancient idolatry, apostacy, and rebellion. They shall be brought to humble themselves before the Lord, to repent of their sins, and to trust in their long-rejected Mediator for salvation. Then he will deliver them, and make their prosperity great.
