And it came to pass, when ye heard the voice out of the midst of the darkness, (for the mountain did burn with fire,) that ye came near unto me, even all the heads of your tribes, and your elders;

Cross-reference

Deuteronomy 4:11 also describes the mountain burning with fire, darkness, and clouds—the same theophany recounted earlier.

Deuteronomy 9:15 mentions the fire on the mountain when Moses came down—referencing the same fiery scene from Moses' perspective.

Exodus 20:18 describes the same Sinai theophany—people seeing thunder, lightning, smoke, and standing afar, matching the fiery darkness here.

Exodus 20:19 records the people's request for Moses to mediate—the immediate sequel to hearing God's voice in the fire.

Hebrews 12:18-21 recalls the terrifying Sinai scene—fire, darkness, tempest—using it to contrast with the new covenant.

Psalm 68:8 Allusion

Psalm 68:8 explicitly says Sinai shook at God's presence—a direct poetic reference to the same event described here.
