Exodus 19:16-24 Then it came to pass on the third day, in the morning, that there were thunderings and lightnings, and a thick cloud on the mountain; and the sound of the trumpet was very loud, so that all the people who were in the camp trembled. And Moses brought the people out of the camp to meet with God, and they stood at the foot of the mountain. Now Mount Sinai was completely in smoke, because the LORD descended upon it in fire. Its smoke ascended like the smoke of a furnace, and the whole mountain quaked greatly. And when the blast of the trumpet sounded long and became louder and louder, Moses spoke, and God answered him by voice. Then the LORD came down upon Mount Sinai, on the top of the mountain. And the LORD called Moses to the top of the mountain, and Moses went up. And the LORD said to Moses, “Go down and warn the people, lest they break through to gaze at the LORD, and many of them perish. Also let the priests who come near the LORD consecrate themselves, lest the LORD break out against them.” But Moses said to the LORD, “The people cannot come up to Mount Sinai; for You warned us, saying, ‘Set bounds around the mountain and consecrate it.’” Then the LORD said to him, “Away! Get down and then come up, you and Aaron with you. But do not let the priests and the people break through to come up to the LORD, lest He break out against them.”
Hebrews 12:18-23 For you have not come to the mountain that may be touched and that burned with fire, and to blackness and darkness and tempest, and the sound of a trumpet and the voice of words, so that those who heard it begged that the word should not be spoken to them anymore. (For they could not endure what was commanded: “And if so much as a beast touches the mountain, it shall be stoned or shot with an arrow.” And so terrifying was the sight that Moses said, “I am exceedingly afraid and trembling.”) But you have come to Mount Zion and to the city of the living God, the heavenly Jerusalem, to an innumerable company of angels, to the general assembly and church of the firstborn who are registered in heaven, to God the Judge of all, to the spirits of just men made perfect,
Exodus 19:11-13 And let them be ready for the third day. For on the third day the LORD will come down upon Mount Sinai in the sight of all the people. You shall set bounds for the people all around, saying, ‘Take heed to yourselves that you do not go up to the mountain or touch its base. Whoever touches the mountain shall surely be put to death. Not a hand shall touch him, but he shall surely be stoned or shot with an arrow; whether man or beast, he shall not live.’ When the trumpet sounds long, they shall come near the mountain.”

We have seen this day that God speaks with man; yet he still lives. Now therefore, why should we die? For this great fire will consume us; if we hear the voice of the LORD our God anymore, then we shall die. For who is there of all flesh who has heard the voice of the living God speaking from the midst of the fire, as we have, and lived?
