Deuteronomy 5:25 (KJV)

And it came to pass, when ye heard the voice out of the midst of the darkness, (for the mountain did burn with fire,) that ye came near unto me, even all the heads of your tribes, and your elders;

And ye said, Behold, the Lord our God hath shewed 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 doth talk with man, and he liveth.

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.

For who is there of all flesh, that hath heard the voice of the living God speaking out of the midst of the fire, as we have, and lived?

Go thou near, and hear all that the Lord our God shall say: and speak thou unto us all that the Lord our God shall speak unto thee; and we will hear it, and do it.
