Deuteronomy 4:10-12 Darby Translation (DARBY)
10 the day that thou stoodest before Jehovah thy God in Horeb, when Jehovah said to me, Gather me the people together, that I may cause them to hear my words, that they may learn them, and fear me all the days that they live upon the earth, and teach them to their children.
11 And ye came near and stood under the mountain; and the mountain burned with fire to the heart of heaven, with darkness, clouds, and obscurity.
12 And Jehovah spoke to you from the midst of the fire: ye heard the voice of the words, but ye saw no form; only [ye heard] a voice.
Deuteronomy 4:10-12 New International Version (NIV)
10 Remember the day you stood before the Lord your God at Horeb, when he said to me, “Assemble the people before me to hear my words so that they may learn to revere me as long as they live in the land and may teach them to their children.” 11 You came near and stood at the foot of the mountain while it blazed with fire to the very heavens, with black clouds and deep darkness. 12 Then the Lord spoke to you out of the fire. You heard the sound of words but saw no form; there was only a voice.
