Deuteronomy 18:16

According to all that thou desiredst of the Lord thy God at
Horeb
This was promised them, in answer to their request at Horeb or Mount Sinai, when the law was delivered to them in the terrible manner it was: in the day of the assembly; in which the tribes were gathered together to receive the law, when they were assembled at the foot of the mount for that purpose:

saying, let me not hear again the voice of the Lord my God;
which was such a voice of words, attended with so much terror, that they that heard entreated the word might not be spoken to them any more, as the apostle says in ( Hebrews 12:19 ) ,

neither let me see this great fire any more, that I die not;
out of which the Lord spoke; the congregation of Israel is here represented speaking as if a single person.
