Deuteronomy 4:11-12

4:11 You approached and stood at the foot of the mountain, a mountain ablaze to the sky above it ¹  and yet dark with a thick cloud. ²  4:12 Then the Lord spoke to you from the middle of the fire; you heard speech but you could not see anything – only a voice was heard. ³ 

¹ tn Heb “a mountain burning with fire as far as the heart of the heavens.” The Hebrew term שָׁמַיִם (shamayim) may be translated “heaven(s)” or “sky” depending on the context.

² tn Heb “darkness, cloud, and heavy cloud.”

³ tn The words “was heard” are supplied in the translation to avoid the impression that the voice was seen.
