Deuteronomy 5:22-24

22“These words the Lord spoke to all your assembly at the mountain from the midst of the fire, of the cloud and of the thick gloom, with a great voice, and He added no more. 1He wrote them on two tablets of stone and gave them to me.

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

24You said, ‘Behold, 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 today that God speaks with man, yet he lives.
