4:42 Anyone who accidentally killed someone 1 without hating him at the time of the accident 2 could flee to one of those cities and be safe.
1 tnHeb “the slayer who slew his neighbor without knowledge.”
2 tnHeb “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.
