Hebrews 12:18

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.

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.

And all the people perceived the thunder and the lightning flashes and the sound of the trumpet and the mountain smoking; and the people perceived it, and they shook and stood at a distance.

“And you came near and stood at the foot of the mountain, and the mountain burned with fire to the very heart of the heavens: darkness, cloud, and dense gloom.

I was standing between Yahweh and you at that time, to declare to you the word of Yahweh; for you were afraid because of the fire and did not go up the mountain. He said,

For if the ministry of condemnation has glory, much more does the ministry of righteousness abound in glory.

Among these are Hymenaeus and Alexander, whom I have handed over to Satan, so that they will be taught not to blaspheme.

For you have not come to a mountain that can be touched and to a blazing fire, and to darkness and gloom and whirlwind,
