“for these, even for the priests.” In the Millennial Kingdom the priests will get a section of land that is 25,000 royal cubits (8.12 miles; 13.06 km) from east to west and 10,000 royal cubits (roughly 3.25 miles; 5.23 km) from north to south. This is very different from how things were in the Old Testament when the priests, who are all also Levites, did not get any land of their own but were assigned cities (Josh. 21:1-42). Every priest was a Levite, a descendent of Jacob’s 3rd son, Levi (Gen. 29:34), but not every Levite was a priest, because the priests were descended from Aaron, who was a great-grandson of Levi (Levi, Kohath, Amram, Aaron; 1 Chron. 6:1-3).
“The side toward the north will be 25,000 in length.” The rectangle for the priests was to have its north and south border be 25,000 cubits long, and its east and west border 10,000 cubits long, and 25,000 royal cubits is just over 8 miles (8.12 miles; 13.06 km), while 10,000 royal cubits is roughly 3.25 miles (5.23 km). For the measurement of the royal cubit, see commentary on Ezekiel 48:8.
“and the sanctuary of Yahweh will be in its middle.” The temple of Yahweh was to be in the middle of the area for the priests, and was thus in the middle of the whole 25,000 cubit square. The square was an offering to Yahweh, but the priest’s section, which contained the temple, was the holiest part of the offering, and was “a most holy place” (Ezek. 48:12).
