Ezekiel 40:10

“And the little chambers of the gate eastward, &c.] Where the man now was, and was measuring; and the like chambers there were in the other gates, and of the same measure; of which chambers (See Gill on “<264007>Ezekiel 40:7”): were three on this side, and three on that side; three on the right side of the porch to the north, and three on the left side of it to the south: they three were of one measure; one reed, or three yards and a half square, as in (<264007>Ezekiel 40:7) and the posts had one measure on this side and on that side; on the right and left, north and south of the inward gate of the porch, which measure was two cubits, (<264009>Ezekiel 40:9).”

“The east gate-building. See Plan III. Ezekiel 40:6 Stairs - Seven in number Ezekiel 40:22. Each threshold of the gate (was) one reed broad (or 9 ft.). The measurements are being taken from East to west, i. e., in depth. Ezekiel 40:7 Every little chamber - The guard-chambers (a) for the use of the Levites who kept watch in the temple. The threshold of the gate by the porch - The second threshold in the easternmost gate-way (c). Porch - Hebrew אולם 'ûlâm; the Septuagint: αἰλάμ ailam; Vulgate: vestibulum. The word probably means porch or portico, connected with “ail” post or pillar. Ezekiel 40:9 The porch is now measured from north to south in “wide.” “The breadth of the entry of the gate”…”

“Chambers - These chambers were for the priests and Levites to lodge in during their ministration. Ezekiel 40:11”

“the little: Eze 40:7 they three: The entrance into the outer court seems to have been through a porch with doors at both ends; and on each side of this porch were three small chambers, or rooms, for the use of the porters, a reed square in size, with a passage of five cubits between them. The common cubit, termed the "cubit of a man," ( Deu 3:11), was about 18 inches; but the cubit used by the angel was, as we learn from Eze 43:13, "a cubit and a hand breadth," or about three inches more than the common cubit, that is 21 inches. Hence the measuring reed, which was "six cubits long, by the cubit and the hand breadth," ( Eze 40:5), must have been about 10+ feet Ezekiel 40:12”
