Deuteronomy 5:22; Deuteronomy 5:23

22 These are the commandments the LORD proclaimed in a loud voice to your whole assembly there on the mountain from out of the fire, the cloud and the deep darkness; and he added nothing more. Then he wrote them on two stone tablets and gave them to me.

23 When you heard the voice out of the darkness, while the mountain was ablaze with fire, all the leaders of your tribes and your elders came to me.
