Deuteronomy 5:22-24

22“The Lord spoke these words with a great voice to all your assembly at the mountain out of the midst of the fire, the cloud, and the thick darkness, and He added no more. He wrote these commandments 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 leaders (heads) of your tribes and your elders;

24and you 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 [still] lives.
