Middos3: 6
הַכִּיּוֹר הָיָה בֵין הָאוּלָם וְלַמִּזְבֵּחַ, וּמָשׁוּךְ כְּלַפֵּי הַדָּרוֹם.  בֵּין הָאוּלָם וְלַמִּזְבֵּחַ שְׁתַּיִם וְעֶשְׂרִים אַמָּה וּשְׁתֵּים עֶשְׂרֵה מַעֲלוֹת הָיוּ שָׁם; רוּם מַעֲלָה חֲצִי אַמָּה, וְשִׁלְחָהּ אַמָּה. אַמָּה אַמָּה וְרֹבֶד שָׁלֹשׁ; וְאַמָּה אַמָּה וְרֹבֶד שָׁלֹשׁ; וְהָעֶלְיוֹנָה אַמָּה אַמָּה וְרֹבֶד אַרְבַּע. רַבִּי יְהוּדָה אוֹמֵר: הָעֶלְיוֹנָה אַמָּה אַמָּה וְרֹבֶד חָמֵשׁ.
The Laver was [located] between the Antechamber and the Altar and was drawn toward the south.  Between the Antechamber and the Altar [were] twenty-two amos and there were twelve steps there; [the] height of [each] step [was] half an amah, and its tread [was] one amah. One amah, one amah, and a landing [of] three amos; and one amah, one amah, and a landing [of] three [amos]; and the uppermost [set]: one amah, one amah [etc.], and a landing [of] four [amos]. R’ Yehudah says: The [steps of the] uppermost [set were] one amah, one amah [etc.], and a landing [of] five amos.
Middos3: 7
פִּתְחוֹ שֶׁל אוּלָם גָּבְהוֹ אַרְבָּעִים אַמָּה וְרָחְבּוֹ עֶשְׂרִים אַמָּה, וְחָמֵשׁ מַלְתְּרָאוֹת שֶׁל מֵילָת הָיוּ עַל גַּבָּיו.  הַתַּחְתּוֹנָה עוֹדֶפֶת עַל הַפֶּתַח אַמָּה מִזֶּה וְאַמָּה מִזֶּה; שֶׁלְּמַעְלָה מִמֶּנָּה עוֹדֶפֶת עָלֶיהָ אַמָּה מִזֶּה וְאַמָּה מִזֶּה. נִמְצֵאת הָעֶלְיוֹנָה שְׁלֹשִׁים אַמָּה, וְנִדְבָּךְ שֶׁל אֲבָנִים הָיָה בֵין כָּל אַחַת וְאַחַת.
[The] entrance of the Antechamber, its height [was] forty amos and its width [was] twenty amos, and five decorated oak beams were above [the entrance].  The bottom [beam] was wider than the entrance [by] one amah on this side and one amah on this side; the [beam] above it was wider than [the first beam by] one amah on this side and one amah on this side. It is found [that] the uppermost [beam was] thirty amos, and a row of stones was between each and every [beam].
