321 Give ear, O heavens, and I will speak; let the earth hear the words of my mouth. 2 May my teaching drop like the rain, my speech condense like the dew; like gentle rain on grass, like showers on new growth. 3 For I will proclaim the name of the Lord; ascribe greatness to our God! 4 The Rock, his work is perfect, and all his ways are just. A faithful God, without deceit, just and upright is he; 5 yet his degenerate children have dealt falsely with him, a perverse and crooked generation. 6 Do you thus repay the Lord, O foolish and senseless people? Is not he your father, who created you, who made you and established you?

7 Remember the days of old, consider the years long past; ask your father, and he will inform you; your elders, and they will tell you. 8 When the Most High apportioned the nations, when he divided humankind, he fixed the boundaries of the peoples according to the number of the gods; 9 the Lord's own portion was his people, Jacob his allotted share.

Matthew Henry's Commentary on Deuteronomy 32:1-9

Commentary on Deuteronomy 32:1-2

(Read Deuteronomy 32:1-2)

Moses begins with a solemn appeal to heaven and earth, concerning the truth and importance of what he was about to say. His doctrine is the gospel, the speech of God, the doctrine of Christ; the doctrine of grace and mercy through him, and of life and salvation by him.

Commentary on Deuteronomy 32:3-6

(Read Deuteronomy 32:3-6)

"He is a Rock." This is the first time God is called so in Scripture. The expression denotes that the Divine power, faithfulness, and love, as revealed in Christ and the gospel, form a foundation which cannot be changed or moved, on which we may build our hopes of happiness. And under his protection we may find refuge from all our enemies, and in all our troubles; as the rocks in those countries sheltered from the burning rays of the sun, and from tempests, or were fortresses from the enemy. "His work is perfect:" that of redemption and salvation, in which there is a display of all the Divine perfection, complete in all its parts. All God's dealings with his creatures are regulated by wisdom which cannot err, and perfect justice. He is indeed just and right; he takes care that none shall lose by him. A high charge is exhibited against Israel. Even God's children have their spots, while in this imperfect state; for if we say we have no sin, no spot, we deceive ourselves. But the sin of Israel was not habitual, notorious, unrepented sin; which is a certain mark of the children of Satan. They were fools to forsake their mercies for lying vanities. All wilful sinners, especially sinners in Israel, are unwise and ungrateful.

Commentary on Deuteronomy 32:7-14

(Read Deuteronomy 32:7-14)

Moses gives particular instances of God's kindness and concern for them. The eagle's care for her young is a beautiful emblem of Christ's love, who came between Divine justice and our guilty souls, and bare our sins in his own body on the tree. And by the preached gospel, and the influences of the Holy Spirit, He stirs up and prevails upon sinners to leave Satan's bondage. In verses 13,14, are emblems of the conquest believers have over their spiritual enemies, sin, Satan, and the world, in and through Christ. Also of their safety and triumph in him; of their happy frames of soul, when they are above the world, and the things of it. This will be the blessed case of spiritual Israel in every sense in the latter day.
