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 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.
