On the third day, when it was morning, there were thunders and lightnings, and a thick cloud on the mountain, and the sound of an exceedingly loud trumpet; and all the people who were in the camp trembled.

Allusion2
A deliberate verbal borrowing without a citation formula.
The 'loud voice, like a trumpet' evokes the Sinai theophany, where God's voice attends 'an exceedingly loud trumpet.' Strong thematic coherence (divine self-revelation announced by trumpet); John casts Patmos as a new Sinai where the prophet receives the word.
High confidence“Out of the throne proceed lightnings, sounds, and thunders” is a direct Sinai-theophany cluster: astrapai kai phonai kai brontai is the fixed triad Revelation repeats at every major hinge (4:5; 8:5; 11:19; 16:18), and it derives from the thunders-and-lightnings of the Sinai descent. Distinctive and recurrent: the three-fold storm formula is a signature Revelation idiom rooting the throne in the mountain of the giving of the Law. LXX Exod 19:16 has phonai kai astrapai — the same lexemes John reorders. Strong on volume and recurrence.
High confidenceEcho3
A fainter, low-volume reuse, carried by recurrence or thematic coherence.
The summoning “voice... like a trumpet” recalls the Sinai theophany, where the trumpet blast accompanies God's self-revelation atop the mountain. Coherence with the broader Sinai background of Rev 4 (the thunder/lightning of v.5 also draws on this verse) strengthens the link; the trumpet-as-divine-voice is a recurring Sinai motif (cf. Exod 20:18; Heb 12:19). Medium because the trumpet in Rev 1:10/4:1 may primarily be conventional apocalyptic angelophany rather than a deliberate Sinai citation.
Medium confidenceThe Sinai theophany 'trumpet blast' that summons Israel before God may stand at the headwaters of the eschatological trumpet of v.52. Volume is low and the link is typological rather than verbal, so this is a faint echo of the trumpet-of-divine-presence tradition.
Low confidenceSinai thunders (qolot, LXX phonai) accompanying theophany undergird the seven thunders 'uttering their voices.' Faint; the thunder-as-voice idiom is widespread.
