Reference for Middot 2:1

הַר הַבַּיִת הָיָה חֲמֵשׁ מֵאוֹת אַמָּה עַל חֲמֵשׁ מֵאוֹת אַמָּה, רֻבּוֹ מִן הַדָּרוֹם, שֵׁנִי לוֹ מִן הַמִּזְרָח, שְׁלִישִׁי לוֹ מִן הַצָּפוֹן, מִעוּטוֹ מִן הַמַּעֲרָב. מְקוֹם שֶׁהָיָה רֹב מִדָּתוֹ, שָׁם הָיָה רֹב תַּשְׁמִישׁוֹ:

The temple mount was five hundred <i>amah</i> [cubit] by five hundred <i>amah</i>, with most of it [its chambers] in the south, second to it [number of chambers] was in the east, third it [number of chambers] was in the north, and the least were in the west. The area which had the most maesure [number of chambers] had the most use.
