Exodus 20:18-21

When the people heard the thunder and the trumpet, and when they saw the lightning and the smoke rising from the mountain, they shook with fear and stood far away from the mountain. Then they said to Moses, “Speak to us yourself, and we will listen. But don’t let God speak to us, or we will die.” Then Moses said to the people, “Don’t be afraid, because God has come to test you. He wants you to respect him so you will not sin.” The people stood far away from the mountain while Moses went near the dark cloud where God was.
