Deuteronomy 32:15-18

But Jeshurun waxed fat, and kicked: Thou art waxed fat, thou art grown thick, thou art become sleek; Then he forsook God who made him, And lightly esteemed the Rock of his salvation. They moved him to jealousy with strange gods; With abominations provoked they him to anger. They sacrificed unto demons, which were no God, To gods that they knew not, To new gods that came up of late, Which your fathers dreaded not. Of the Rock that begat thee thou art unmindful, And hast forgotten God that gave thee birth.
