Deuteronomy 4:12

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.

Deuteronomy 4:42

4:42 Anyone who accidentally killed someone without hating him at the time of the accident could flee to one of those cities and be safe.

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

tn Heb “the slayer who slew his neighbor without knowledge.”

tn Heb “yesterday and a third (day).” The point is that there was no animosity between the two parties at the time of the accident and therefore no motive for the killing.
