Halakhah for Kelim 1:8
לִפְנִים מִן הַחוֹמָה מְקֻדָּשׁ מֵהֶם, שֶׁאוֹכְלִים שָׁם קָדָשִׁים קַלִּים וּמַעֲשֵׂר שֵׁנִי. הַר הַבַּיִת מְקֻדָּשׁ מִמֶּנּוּ, שֶׁאֵין זָבִים וְזָבוֹת, נִדּוֹת וְיוֹלְדוֹת נִכְנָסִים לְשָׁם. הַחֵיל מְקֻדָּשׁ מִמֶּנּוּ, שֶׁאֵין גּוֹיִם וּטְמֵא מֵת נִכְנָסִים לְשָׁם. עֶזְרַת נָשִׁים מְקֻדֶּשֶׁת מִמֶּנּוּ, שֶׁאֵין טְבוּל יוֹם נִכְנָס לְשָׁם, וְאֵין חַיָּבִים עָלֶיהָ חַטָּאת. עֶזְרַת יִשְׂרָאֵל מְקֻדֶּשֶׁת מִמֶּנָּה, שֶׁאֵין מְחֻסַּר כִּפּוּרִים נִכְנָס לְשָׁם, וְחַיָּבִין עָלֶיהָ חַטָּאת. עֶזְרַת הַכֹּהֲנִים מְקֻדֶּשֶׁת מִמֶּנָּה, שֶׁאֵין יִשְׂרָאֵל נִכְנָסִים לְשָׁם אֶלָּא בִשְׁעַת צָרְכֵיהֶם, לִסְמִיכָה לִשְׁחִיטָה וְלִתְנוּפָה:
Inside the wall [of Jerusalem] is more holy than these, because there the less holy [offerings] and the second tithe are eaten. The Temple Mount has greater sanctity, because men and women with discharges, menstruating women, and women who have given birth may not enter there. The outer wall of the Temple courtyard has higher sanctity, because gentiles and people contaminated with corpse impurity may not enter there. The women's courtyard has higher sanctity, because a <em>tevul yom</em> may not enter there, but they are not liable for a sin offering for doing so. The Israelites' courtyard has higher sanctity, because one who lacks atonement may not enter there, and is liable for a sin offering for doing so. The priests' courtyard has higher sanctity, because the Israelites may not enter there except at the time of their [ritual] requirements: the laying on of hands, the slaughter, and the wave-offering.
