Parallel
Exodus 20:18
Brenton's English Septuagint · Berean Standard Bible
And all the people perceived the thundering, and the flashes, and the voice of the trumpet, and the mountain smoking; and all the people feared and stood afar off,
When all the people witnessed the thunder and lightning, the sounding of the ram’s horn, and the mountain enveloped in smoke, they trembled and stood at a distance.
