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 48:21
And the residue - for the prince - His portion was alongside that of the Levites, from west to east; these were on each side twenty-five thousand cubits in length, from the east to the west. by twelve thousand five hundred cubits in breadth from north to south. The space both above and below was equal, between the tribe of Judah and that of Benjamin to north and south; and the portion of the Levites, which had Judah and Benjamin to the north and south, and the portion of the prince to the east and to the west. See the map.
John Gill on Ezekiel 48:26
And by the border of Issachar, from the east side unto the west side, Zebulun a portion. In like manner, next to Issachar's inheritance, and bordering on it, shall be Zebulun's; who shall be no more a haven for ships, having a different situation and allotment; and may describe such Christians as dwell in Christ, and he in them.
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 48:23
And the rest of the tribes shall receive [portions] south of that strip, Benjamin alongside it, and beside him Simeon, beside him Issachar, beside him Zebulun, and beside him Gad. Gad is therefore at the southern boundary of the land of Israel.
