Deuteronomy 5:22-24

22“These words the Lord spoke to all your assembly, in the mountain from the midst of the fire, the cloud, and the thick darkness, with a loud voice; and He added no more. And He wrote them on two tablets of stone and gave them to me.

23“So it was, when you heard the voice from the midst of the darkness, while the mountain was burning with fire, that you came near to me, all the heads of your tribes and your elders.

24And you said: ‘Surely the Lord our God has shown us His glory and His greatness, and we have heard His voice from the midst of the fire. We have seen this day that God speaks with man; yet he still lives.
