Exodus 20:18
When the people saw the thunder and lightning and heard the trumpet and saw the mountain in smoke, they trembled with fear. They stayed at a distance. The community's response to the theophany is precisely what God anticipated and Moses promised: trembling. The sight and sound of God's presence — thunder, lightning, trumpet, smoke — produce fear in the created before the Creator. The staying at a distance is not disobedience but appropriate recognition of the boundary between the holy and the ordinary. Hebrews 12:21 says the sight was so terrifying that Moses said I am trembling with fear — the human response to raw divine holiness, even for the one who stands in the divine presence most regularly, is trembling. The trembling of the community is the right response to the reality of who is present at the mountain.
