Jamieson-Fausset-Brown on Ezekiel 48:26
Issachar--Its ancient portion had been on the plain of Esdraelon. Compared (Gen 49:14) to "a strong ass crouching between two burdens," that is, tribute and tillage; never meddling with wars except in self-defense.
Adam Clarke on Ezekiel 48:28
From Tamar - in Kadesh - The former was on the south of the Dead Sea; and the latter, or Kadesh-Barnea, was still farther south, and at the extremity of the portion of Gad, which was the most southern tribe, as Dan was the most northern.
John Gill on Ezekiel 48:28
And by the border of Gad, at the south side southward,.... Of the sanctuary of the Lord, of the portion of the priests and Levites, of the city, and what belonged to that, and of the prince's portion. The description begins at the northern part of the land, and ends in the southern:
the border shall be even from Tamar unto the waters of strife in Kadesh; and to the river toward the great sea; See Gill on Ezekiel 47:19.
Tyndale Open Study Notes on Ezekiel 48:21-29
The area filling out the rest of the central portion to the east and west of the holy square was assigned to the prince. The prince was more important than the rest of the laity, but he was below the priests and Levites. The same message was delivered by the architecture of the Temple complex.
Rashi on Ezekiel 48:28
And alongside the border of Gad its southern boundary.
from Tamar to the waters of Meribath-kadesh, to the brook [It starts] from Jericho, the city of date palms (הַתְּמָרִים), in the eastern corner, and comes to the west to the waters of Meribath-kadesh, and proceeds until the brook of Egypt, which empties into the Great Sea in the southwestern corner.
