Exodus 20:18-20

18And 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,

19and said to Moses, Speak thou with us, and we will hear; but let not 1God speak with us, lest we die.

20And Moses said to the people, Fear not; for 2God is come to prove you, and that his fear may be before you, that ye sin not.
