Exodus 19:18

The whole mount quaked greatly There cannot be a more grand, awful, and majestic description than this of the descent of Jehovah upon mount Sinai. We can scarcely read it without trembling; and all the tremendous majesty of God appears before our eyes. The psalmist seems to have conceived a most high idea of God from it: “O God, when thou wentest forth before thy people, when thou didst march through the wilderness; the earth shook, the heavens also dropped at the presence of God, the God of Israel,” Psalms 68:7.
