Exodus 20:18-21 - The People's Reaction
18 And all the people saw the thunderings, and the flames, and the sound of the trumpet, and the mountain smoking; and when the people saw it, they trembled, and stood afar off, 19 and said to Moses, Speak thou with us, and we will hear; but let not God speak with us, lest we die.
20 And Moses said to the people, Fear not; for God is come to prove you, and that his fear may be before you, that ye sin not. 21 And the people stood afar off, and Moses drew near to the obscurity where God was.
