Deuteronomy 32:15-23

15Jeshurun grew fat and kicked; filled with food, they became heavy and sleek. They abandoned the God who made them and rejected the Rock their Savior. 16They made him jealous with their foreign gods and angered him with their detestable idols. 17They sacrificed to false gods, which are not God— gods they had not known, gods that recently appeared, gods your ancestors did not fear. 18You deserted the Rock, who fathered you; you forgot the God who gave you birth. 19The Lord saw this and rejected them because he was angered by his sons and daughters. 20“I will hide my face from them,” he said, “and see what their end will be; for they are a perverse generation, children who are unfaithful. 21They made me jealous by what is no god and angered me with their worthless idols. I will make them envious by those who are not a people; I will make them angry by a nation that has no understanding. 22For a fire will be kindled by my wrath, one that burns down to the realm of the dead below. It will devour the earth and its harvests and set afire the foundations of the mountains. 23“I will heap calamities on them and spend my arrows against them.
