Eze 45:1 Moreover, when ye shall divide by lot the land for inheritance, ye shall offer an oblation unto the LORD, an holy portion of the land: the length shall be the length of five and twenty thousand reeds, and the breadth shall be ten thousand. This shall be holy in all the borders thereof round about.
Eze 45:2 Of this there shall be for the sanctuary five hundred in length, with five hundred in breadth, square round about; and fifty cubits round about for the suburbs thereof.
Eze 45:3 And of this measure shalt thou measure the length of five and twenty thousand, and the breadth of ten thousand: and in it shall be the sanctuary and the most holy place.
Eze 45:4 The holy portion of the land shall be for the priests the ministers of the sanctuary, which shall come near to minister unto the LORD: and it shall be a place for their houses, and an holy place for the sanctuary.
Eze 45:5 And the five and twenty thousand of length, and the ten thousand of breadth, shall also the Levites, the ministers of the house, have for themselves, for a possession for twenty chambers.
Eze 45:6 And ye shall appoint the possession of the city five thousand broad, and five and twenty thousand long, over against the oblation of the holy portion: it shall be for the whole house of Israel.
Eze 45:7 And a portion shall be for the prince on the one side and on the other side of the oblation of the holy portion, and of the possession of the city, before the oblation of the holy portion, and before the possession of the city, from the west side westward, and from the east side eastward: and the length shall be over against one of the portions, from the west border unto the east border.
five and twenty thousand reeds, etc. — So English Version rightly fills the ellipsis (compare Note, see on Eze_42:16). Hence “cubits” are mentioned in Eze_45:2, not here, implying that there alone cubits are meant. Taking each reed at twelve feet, the area of the whole would be a square of sixty miles on each side
. The whole forming a square betokens the settled stability of the community and the harmony of all classes. “An holy portion of the land” (Eze_45:1) comprised the whole length, and only two-fifths of the breadth. The outer territory in its distribution harmonizes with the inner and more sacred arrangements of the sanctuary. No room is to be given for oppression (see Eze_45:8), all having ample provision made for their wants and comforts. All will mutually co-operate without constraint or contention. - Jamieson Fausset and Brown
