Allusion1
A deliberate verbal borrowing without a citation formula.
'the house was filled with smoke' (kapnos) at Isaiah's throne-vision is the closest verbal match for 'filled with smoke,' linking theophany-judgment to temple glory. The word 'smoke' (not 'cloud') tilts Rev toward Isaiah 6 over Exod 40.
High confidenceEcho1
A fainter, low-volume reuse, carried by recurrence or thematic coherence.
The shaking of 'the place' (the praying assembly) after the prayer also recalls Isa 6:4, where the thresholds/foundations of the temple shook at the divine voice amid the seraphic praise. A theophanic shaking echo; low and contested.
