Hebrews 12:19

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.

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.

Then they said to Moses, “Speak to us yourself, and we will listen; but let not God speak to us, lest we die.”

“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,

“And He will send forth His angels with a great trumpet and they will gather together His elect from the four winds, from one end of the sky to the other.

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,

See to it that you do not refuse Him who is speaking. For if those did not escape when they refused him who warned them on earth, much less will we escape who turn away from Him who warns from heaven.
