Deuteronomy 32:15-18

15“But Jeshurun grew fat, and kicked; you grew fat, stout, and sleek; then he forsook God who made him and scoffed at the Rock of his salvation. 16They stirred him to jealousy with strange gods; with abominations they provoked him to anger. 17They sacrificed to demons that were not God, to gods they had never known, to new gods that had come recently, whom your fathers had never dreaded. 18You were unmindful of the Rock that bore you, and you forgot the God who gave you birth.
