Quotation1
A formal citation — high verbal volume, often introduced by a saying-formula.
Formula-cited ('as it is written') in v.8: 'God gave them a spirit of stupor (pneuma katanyxeos)' is verbatim from Isa 29:10 LXX, 'the LORD has poured out on you a spirit of deep sleep.' Supplies the head phrase of the conflated citation about Israel's hardening.
High confidenceAllusion1
A deliberate verbal borrowing without a citation formula.
The Lord pouring out a 'spirit of deep sleep,' closing eyes, parallels the strong delusion God sends so that they believe what is false. Judicial stupefaction is the shared idea.
