Posts of threescore cubits - Sixty cubits were the length of a series of columns. This gives us another feature of the gate-building. Between the porch (E) and the two most western guard-chambers was a space of five cubits (through which the road passed), forming a kind of hall with columns along the sides. This hall is called the "arches" Ezekiel 40:16. A hall of the same dimensions was between the boundary wall and eastern guard-chambers Ezekiel 40:31. It is probable that in one of these halls (that of the eastern gateway of the inner court) the prince "ate bread" on solemn festivals Ezekiel 44:3.
Unto the post of the court round about the gate - This hall or colonnade extended the whole breadth of the building to the pavement (Ezekiel 40:18, H, Plan II). Outside the building on the pavement was a series of pillars.

He made also posts of threescore cubits,.... Jerom thinks, that between the outward wall which surrounded this building, and the building itself, these posts or pillars were placed for ornament, which took up the space of sixty cubits; but rather these design the posts or columns of the gate, which supported the arch over it, on which were rooms or stories, and these were sixty cubits high; for of their height is this measure to be understood. So the Targum,
"and he made posts, sixty cubits was their height;''
in the Targum, in the Polyglot Bible by Montanus, it is,
"and he made sixty posts, their height a cubit:''
and to this agree Jarchi and Kimchi; these were thirty five yards high, the height of the temple ordered to be built by Cyrus, Ezra 6:3. The man that measured is said to "make" these posts, he being the builder as well as the measurer of this edifice; and might be said to make these as, by measuring, he pointed out the size and proportion of them: these posts may design the true members of Gospel churches, such who are pillars in the house of God; of which see more on Ezekiel 40:16, compare the phrase of "making" these posts or pillars with Revelation 3:12,
even unto the post of the court round about the gate; that is, there was the same measure to every post or pillar in every court, at every gate round about; at the southern and northern gates, as at this eastern one; they were all exactly of the same measure as the posts in this; so Jarchi and Kimchi interpret it.

He made - Measured, and thereby shewed what kind of posts they should be. Threescore cubits - Probably this refers to the height of this gate built up two stories above the arch, and the posts in their height are only mentioned, but imply all the rest of the building over the east gate. Unto the post - These high columns, on the inner front of this gate were so disposed, that the last on each side was very near the first post, or pillar of the court on either side of the gate, and so the posts and buildings laid on those posts joined on each side of this gate.
