Deuteronomy 4:10-12 21st Century King James Version (KJ21)
10 especially the day that thou stoodest before the Lord thy God in Horeb, when the Lord said unto me, ‘Gather Me the people together, and I will make them hear My words, that they may learn to fear Me all the days that they shall live upon the earth, and that they may teach their children.’
11 And ye came near and stood under the mountain; and the mountain burned with fire unto the midst of heaven, with darkness, clouds, and thick darkness.
12 And the Lord spoke unto you out of the midst of the fire. Ye heard the voice of the words, but saw no similitude; 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.
