Parallel
Numbers 35:12
Clementine Vulgate · Berean Standard Bible
in quibus cum fuerit profugus, cognatus occisi non poterit eum occidere, donec stet in conspectu multitudinis, et causa illius judicetur.
You are to have these cities as a refuge from the avenger, so that the manslayer will not die until he stands trial before the assembly.
