Deuteronomy 5:23 Meaning and Commentary

Deuteronomy 5:23

And it came to pass, when ye heard the voice out of the midst
of the darkness
The thick darkness, where God was, and with which the mountain was covered, ( Exodus 20:21 )

for the mountain did burn with fire;
which is a reason both why the Lord spoke out of the midst of the fire, the mountain on which he descended burning with it and also for his speaking out of the midst of darkness, because not only a thick cloud covered the mountain, but it was altogether on a smoke, which ascended as the smoke of a furnace, ( Exodus 19:16 Exodus 19:18 )

that ye come near unto me, even all the heads of your tribes and your
elders;
or wise men, as the Targum of Jonathan; by which it appears, that not only the common people were frightened at what they heard and saw on Mount Sinai, but those of the first rank and eminence among them, who were the most famous for their authority and wisdom.

Deuteronomy 5:23 In-Context

21 Thou shalt not desire thy neighbour’s wife, neither shalt thou covet thy neighbour’s house, his field or his manslave or his maidslave, his ox or his ass or any thing that is thy neighbour’s.
22 These words the LORD spoke unto all your congregation in the mount out of the midst of the fire, of the cloud, and of the thick darkness, with a great voice, and he added no more. And he wrote them in two tables of stone and delivered them unto me.
23 And it came to pass when ye heard the voice out of the midst of the darkness and saw the mountain that burned with fire that ye came near unto me, even all the princes of your tribes and your elders;
24 and ye said, Behold, the LORD our God has shown us his glory and his greatness, and we have heard his voice out of the midst of the fire; we have seen this day that God does talk with man, and he lives.
25 Now, therefore, why should we die? For this great fire will consume us; if we hear the voice of the LORD our God any more, then we shall die.
