Komentarz do Ezechiela 40:18

And the balcony was to the side of the gates The top of the gates of the Court separated the balcony, so that it did not go around the entire Court, and [thus the balcony] was to the sides of the gate from this side and from that side, parallel to the top of the gates.

the base of the balcony [Heb. הַתַּחְתּוֹנָה.] This word is different from every תַּחְתּוֹנָה in the Scriptures, for everywhere the accent is on the “nun,” whereas here, it is on the “tav” [so that the word is essentially תַּחְתּוֹן]. We learn that this תַּחְתּוֹנָה was not a balcony that is under another one but was one balcony, and the base of this balcony paralleled the top of the gate. The “hey” of תַּחְתּוֹנָה is like the “hey” of בֵּיתָה and like the “hey” of עֶזְרָתָה, and of חֶלְאָתָה, each of which is superfluous.
