Commento su Numeri 34:21

למטה בנימין, “of the tribe of Binyamin;” here Binyamin is listed as if the third of the tribes, seeing that these three tribes in the future would cede of their ancestral lands to the Levites all at once, as recorded in the Book of Joshua: 21,4: ויהי לבני אהרן הכהן מן הלוים, ממאה יהודה, וממטה שמעון וממטה בנימין בגורל ערים שלש עשר, “to the descendants of Aaron the priest, there fell by lot 13 towns from the tribe of Yehudah, the tribe of Shimon, and the tribe of Binyamin.” This is why they were lumped together by Moses already at this point.
