Deuteronomy 4:10-13

10The day that you stood before Adonai your God in Horeb, Adonai said to me, ‘Gather the people to Me and I will make them hear My words, so that they learn to fear Me all the days that they live on the earth, and so that they teach their children.’

11“You came near and stood at the bottom of the mountain while the mountain was blazing with fire up to the heart of the heavens—darkness, cloud, and fog.

12Adonai spoke to you from the midst of the fire. The sound of words you heard, but a form you did not see—only a voice.

13He declared to you His covenant, which He commanded you to do—the Ten Words—and He wrote them on two tablets of stone.
