Deuteronomy 5:22-24

22“These words the Lord spoke to your whole assembly at the mountain from the midst of the fire, from the cloud, and from the thick darkness, with a great voice, and He added nothing 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 approached 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 mankind, yet he lives.
