Deuteronomy 32:15-17

15 "The LORD's people grew rich, but rebellious; they were fat and stuffed with food. They abandoned God their Creator and rejected their mighty savior.

16 Their idolatry made the LORD jealous; the evil they did made him angry.

17 They sacrificed to gods that are not real, new gods their ancestors had never known, gods that Israel had never obeyed.
