Deuteronomy 5:22-24

Thomson(i) 22 These are the injunctions which the Lord delivered verbally, to all your congregation, at the mount, out of the midst of the fire. There was darkness, thick darkness, a turbid tempest, and a loud voice. And he added no more. And having written them on two tables of stone, he gave them to me. 23 Now when you heard the voice from the midst of the fire [the mountain indeed was burning with fire] you came to me, even all the leaders of your tribes, and your elders, 24 and said, Behold the Lord our God hath shewn us his glory, and we have heard his voice from the midst of the fire. We have this day seen that God can speak to man, and he may live.
