20 18 Now when all the people perceived the thunderings and the lightnings and the sound of the trumpet and the mountain smoking, the people were afraid and trembled; and they stood afar off, 20 19 and said to Moses, "You speak to us, and we will hear; but let not God speak to us, lest we die." 20 20 And Moses said to the people, "Do not fear; for God has come to prove you, and that the fear of him may be before your eyes, that you may not sin." - Laws about Altars. Ex.20.21-26
20 21 And the people stood afar off, while Moses drew near to the thick darkness where God was.
