Matthew Poole and continuators on Ezekiel 40:17

17 Then brought he me into the outward court, and lo, there were chambers , and a pavement made for the court round about: thirty chambers were upon the pavement.

So called in regard of the more inward Court, between that where he was and the Temple it self, this Court here, called the outward Court, was at least the second, about the Temple, as you go through the first, and greatest Court, or floor encompassed with that wall of one reed high, and one thick, through the second which is the Court of the people, and which probably is this in our text.

Not only lodging rooms for the Priests, but also storehouses for Tithes and Offerings, these were Treasuries, and so rendered by some.

'Twas not laid as we see some Courts before great Houses with us, in a fair walk up from the gate to the door of the House, but the whole floor of this Court was thus paved.

That is fifteen on the Southside of the gate, and fifteen on the North-side, built over the pavement.

A very beautiful floor laid with cheker work, as some say of Marble, or of Porphyry, which is much richer.
