Ezekiel 40:30

And the arches round about were five and twenty cubits long,.... That is, high; this was the height of them; these were the frontispiece of the gate to the inner court without, and faced the outward court, as appears by the following verse; these were a kind of portico over the eight steps to this gate after mentioned; they were fourteen yards and three inches high, from the bottom to the top of them:

and five cubits broad; two yards and a half, one foot and three inches; and which very probably were the breadth of the steps that came up to them: none of these arches were in the second temple, as Lipman m observes.
