Exodus 20:18-20

18All the people heard the thunder and saw the lightning. They heard the blast of the ram’s horn and saw the mountain covered with smoke. So they shook with fear and stood at a distance.

19Then they said to Moses, “You speak to us, and we’ll listen. But don’t let God speak to us, or we’ll die!”

20Moses answered the people, “Don’t be afraid! God has come only to test you, so that you will be in awe of him and won’t sin.”
