Hebrews 12:19 - Matthew Poole's English Annotations on the Holy Bible

And the sound of a trumpet; which was most shrill and dreadful, it sounded long, and waxed louder and louder, giving a fearful alarm unto Israel to draw near to the Lord to hear his law to them, and covenant with them, and to see a type of their doom, if they transgressed it, in an obscure representation of the general judgment, Exodus 19:16,19 Exodus 20:18; compare 1 Thessalonians 4:16 2 Thessalonians 1:7-9. And the voice of words: after which alarm, the Angel of the covenant uttered his voice out of the fire most majestically, distinctly, and loudly, and spake to Israel in their own language the ten words, or commandments, that they might hear and understand them, so as they sensed them to be dreadful for their sound and matter, Exodus 20:1-20 Deuteronomy 4:10,12,13 5:1-27. Which voice they that heard entreated that the word should not be spoken to them any more: the people, being overwhelmed with the majesty and dreadfulness of that voice, deprecated any more such for matter or manner of manifestation to them, Exodus 20:19 Deuteronomy 5:23-26 18:16. And therefore desired Moses to speak to them God's law, and that God might speak no more.
