13 He put him on the high places of the earth, his food was the increase of the field; honey he gave him out of the rock and oil out of the hard rock; 14 Butter from his cows and milk from his sheep, with fat of lambs and sheep of Bashan, and goats, and the heart of the grain; and for your drink, wine from the blood of the grape.

15 But Jeshurun became fat and would not be controlled: you have become fat, you are thick and full of food: then he was untrue to the God who made him, giving no honour to the Rock of his salvation.

Matthew Henry's Commentary on Deuteronomy 32:13-15

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.

Commentary on Deuteronomy 32:15-18

(Read Deuteronomy 32:15-18)

Here are two instances of the wickedness of Israel, each was apostacy from God. These people were called Jeshurun, "an upright people," so some; "a seeing people," so others: but they soon lost the reputation both of their knowledge and of their righteousness. They indulged their appetites, as if they had nothing to do but to make provision for the flesh to fulfil the lusts of it. Those who make a god of themselves, and a god of their bellies, in pride and wantonness, and cannot bear to be told of it, thereby forsake God, and show they esteem him lightly. There is but one way of a sinner's acceptance and sanctification, however different modes of irreligion, or false religion, may show that favourable regard for other ways, which is often miscalled candid. How mad are idolaters, who forsake the Rock of salvation, to run themselves upon the rock of perdition!
