Parashas Masei · Passuk 35:28 · TT note 2
Chabad.org — English translation + Rashi
Torah Temimah points to Makkos 11b (TT note on “אֶל אֶרֶץ אֲחֻזָּתוֹ”).
English: It was taught: If he died before the High Priest died, they bring his bones to his ancestral graves, for it is written “the murderer shall return to the land of his possession” — what dwelling is in the land of his possession? Say: burial.
Posthumous return of the exile’s bones to the family plot.
Even if the unintentional killer dies in the city of refuge before the High Priest, his remains are transferred to the ancestral burial ground as the fulfillment of “return to the land of his possession.”
