Verse 19. And the voice of a trumpet. Ex 19:19. The sound of the trumpet amidst the tempest was fitted to increase the terror of the scene.

And the voice of words. Spoken by God, Ex 19:19. It is easy to conceive what must have been the awe produced by a voice uttered from the midst of the tempest so distinct as to be heard by the hundreds of thousands of Israel, when the speaker was invisible.

Which voice they that heard, etc. Ex 20:18,19. It was so fearful and overpowering, that the people earnestly prayed that if they must be addressed it might be by the familiar voice of Moses, and not by the awful voice of the Deity.
