26 I thought to scatter them and blot out the memory of them from humankind; 27 but I feared provocation by the enemy, for their adversaries might misunderstand and say, "Our hand is triumphant; it was not the Lord who did all this." 28 They are a nation void of sense; there is no understanding in them. 29 If they were wise, they would understand this; they would discern what the end would be. 30 How could one have routed a thousand, and two put a myriad to flight, unless their Rock had sold them, the Lord had given them up? 31 Indeed their rock is not like our Rock; our enemies are fools. 32 Their vine comes from the vinestock of Sodom, from the vineyards of Gomorrah; their grapes are grapes of poison, their clusters are bitter; 33 their wine is the poison of serpents, the cruel venom of asps. 34 Is not this laid up in store with me, sealed up in my treasuries? 35 Vengeance is mine, and recompense, for the time when their foot shall slip; because the day of their calamity is at hand, their doom comes swiftly. 36 Indeed the Lord will vindicate his people, have compassion on his servants, when he sees that their power is gone, neither bond nor free remaining. 37 Then he will say: Where are their gods, the rock in which they took refuge, 38 who ate the fat of their sacrifices, and drank the wine of their libations? Let them rise up and help you, let them be your protection!

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.
