Deuteronomy 4:33 Meaning and Commentary

Deuteronomy 4:33

Did [ever] people hear the voice of God speaking out of the
midst of fire
None ever heard the voice of God as they did, much less speaking such words as they heard, and still less out of the midst of fire, which was their case, ( Deuteronomy 4:12 Deuteronomy 4:15 )

as thou hast heard, and live?
which was stranger still, when they might have expected they should, and doubtless feared they would be, as it was wonderful they were not, consumed by it.

Deuteronomy 4:33 In-Context

31 Because the Lord thy God a God of pity: he will not forsake thee, nor destroy thee; he will not forget the covenant of thy fathers, which the Lord sware to them.
32 Ask of the former days which were before thee, from the day when God created man upon the earth, and at the end of heaven to the other end of heaven, if there has happened any thing like to this great event, if such a thing has been heard:
33 if a nation have heard the voice of the living God speaking out of the midst of the fire, as thou hast heard and hast lived;
34 if God has assayed to go and take to himself a nation out of the midst of nation with trial, and with signs, and with wonders, and with war, and with a mighty hand, and with a high arm, and with great sights, according to all the things which the Lord our God did in Egypt in thy sight.
35 So that thou shouldest know that the Lord thy God he is God, and there is none beside him.
