321 Give ear, O heavens, to my voice; let the earth take note of the words of my mouth: 2 My teaching is dropping like rain, coming down like dew on the fields; like rain on the young grass and showers on the garden plants: 3 For I will give honour to the name of the Lord: let our God be named great. 4 He is the Rock, complete is his work; for all his ways are righteousness: a God without evil who keeps faith, true and upright is he. 5 They have become false, they are not his children, the mark of sin is on them; they are an evil and hard-hearted generation. 6 Is this your answer to the Lord, O foolish people and unwise? Is he not your father who has given you life? He has made you and given you your place.

7 Keep in mind the days of the past, give thought to the years of generations gone by: go to your father and he will make it clear to you, to the old men and they will give you the story. 8 When the Most High gave the nations their heritage, separating into groups the children of men, he had the limits of the peoples marked out, keeping in mind the number of the children of Israel. 9 For the Lord's wealth is his people; Jacob is the land of his heritage.

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.
