Hebrews 12:19
And the sound of a trumpet, and the voice of words; which voice they that heard intreated that the word should not be spoken to them any more: And the sound of a trumpet, and the voice of words; which voice they that heard intreated that the word should not be spoken to them any more:
The verse describes part of the terror of Mount Sinai that Christians have not come to. The sound of a trumpet and the spoken words there were so fearful that the hearers begged that no further word be spoken to them. They could not endure what was commanded, including the penalty of death for even a beast touching the mountain. The sight was so terrible that even Moses feared and quaked.
This fearful experience stands in contrast to having come to Mount Zion, and to the city of the living God, the heavenly Jerusalem, and to an innumerable company of angels, to the general assembly and church of the firstborn written in heaven, and to God the Judge of all, and to the spirits of just men made perfect, and to Jesus the mediator of the new covenant, and to the blood of sprinkling that speaks better things than that of Abel. Even the thunder and lightning of Sinai cannot move those who reject the plain truths of God's word.
