פירוש על יחזקאל 41:12

And the structure that was before the fortress, etc. The width of the entire structure on the western side - the width of the House and the thickness of the northern and southern wall, with the northern and southern cells, and the thickness of their walls on the north and on the south - equaled seventy cubits, and so too it was in the Second Temple. And so we learned in Tractate Middoth (4:7) about the western wall: “From north to south - seventy cubits,” and it computes the calculation.

the fortress [Heb. הַגִּזְרָה.] Jonathan renders: the fortress. And I say that the tall House was called [the fortress] and that the low cells that were around it were called “the structure.” Menahem, however, (page. 54) interpreted גִּזְרָה as a chamber.

the side that was toward the west. [Heb. דֶרֶךְ יָם, lit. the way of the (Mediterranean) Sea.] The western side.
