ex 20:18-21
When the people witnessed the thunder and lightning, the trumpet blast and the mountain smoking, they all feared and trembled. So they took up a position much farther away and said to Moses, "You speak to us, and we will listen; but let not God speak to us, or we shall die." Moses answered the people, "Do not be afraid, for God has come to you only to test you and put his fear upon you, lest you should sin." Still the people remained at a distance, while Moses approached the cloud where God was.
