Deuteronomy 5:22-24

22"These words the Lord spoke to all your assembly at the mountain out of 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.

23And as soon as you heard the voice out of 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.

24And you said, 'Behold, the Lord our God has shown us his glory and greatness, and we have heard his voice out of the midst of the fire. This day we have seen God speak with man, and man still live.
