Parallel
Numbers 35:28
Clementine Vulgate · Berean Standard Bible
Debuerat enim profugus usque ad mortem pontificis in urbe residere. Postquam autem ille obierit, homicida revertetur in terram suam.
because the manslayer must remain in his city of refuge until the death of the high priest. Only after the death of the high priest may he return to the land he owns.
