Hebrews 12:18-21

18For you have not come to the mountain that may be touched and that burned with fire, and to blackness and darkness and tempest,

19and the sound of a trumpet and the voice of words, so that those who heard it begged that the word should not be spoken to them anymore.

20(For they could not endure what was commanded: “And if so much as a beast touches the mountain, it shall be stoned or shot with an arrow.”

21And so terrifying was the sight that Moses said, “I am exceedingly afraid and trembling.”)
