Deuteronomy 4:11 MSG

[11] You gathered. You stood in the shadow of the mountain. The mountain was ablaze with fire, blazing high into the very heart of Heaven. You stood in deep darkness and thick clouds. God spoke to you out of the fire. You heard the sound of words but you saw nothing—no form, only a voice. He announced his covenant, the Ten Words, by which he commanded you to live. Then he wrote them down on two slabs of stone.
