Deuteronomy 32:15

15 Jeshurun put on weight and bucked; you got fat, became obese, a tub of lard. He abandoned the God who made him, he mocked the Rock of his salvation.

Deuteronomy 32:15 In-Context

13 God lifted him on to the hilltops, so he could feast on the crops in the fields. He fed him honey from the rock, oil from granite crags,
14 Curds of cattle and the milk of sheep, the choice cuts of lambs and goats, Fine Bashan rams, high-quality wheat, and the blood of grapes: you drank good wine!
15 Jeshurun put on weight and bucked; you got fat, became obese, a tub of lard. He abandoned the God who made him, he mocked the Rock of his salvation.
16 They made him jealous with their foreign newfangled gods, and with obscenities they vexed him no end.
17 They sacrificed to no-god demons, gods they knew nothing about, The latest in gods, fresh from the market, gods your ancestors would never call "gods."
