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. 16 The honour which was his they gave to strange gods; by their disgusting ways he was moved to wrath. 17 They made offerings to evil spirits which were not God, to gods who were strange to them, which had newly come up, not feared by your fathers. 18 You have no thought for the Rock, your father, you have no memory of the God who gave you birth.
Matthew Henry's Commentary on Deuteronomy 32:15-18
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!
