So it happened on the third day, when it was morning, that there were thunder and lightning flashes and a thick cloud upon the mountain and a very loud trumpet sound, so that all the people who were in the camp trembled.
Exodus 19:14 So Moses went down from the mountain to the people and set the people apart as holy, and they washed their garments.

Exodus 19:16 So it happened on the third day, when it was morning, that there were thunder and lightning flashes and a thick cloud upon the mountain and a very loud trumpet sound, so that all the people who were in the camp trembled.
Exodus 19:17 And Moses brought the people out of the camp to meet God, and they stood at the foot of the mountain.
Exodus 19:18 Now Mount Sinai was all in smoke because Yahweh descended upon it in fire; and its smoke ascended like the smoke of a furnace, and the whole mountain trembled violently.
The verse centers on "light", "happened", "third", "morning", "thunder", "lightning", "flashes", and "thick". It is saying that the verse draws attention to "light" and "happened", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 15's "And he said to the people Be..." into verse 17's "And Moses brought the people out of...", so "light" and "happened" belong inside that flow. In Exodus context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "light" and "happened" with trust shaped by these words, not by a vague optimism outside the passage.
